Man page 1 : xterm

The following resources are specified as part of the vt100 widget (class VT100). They are specified by patterns such as "XTerm.vt100.NAME".

If your xterm is configured to support the "toolbar", then those patterns need an extra level for the form-widget which holds the toolbar and vt100 widget. A wildcard between the top-level "XTerm" and the "vt100" widget makes the resource settings work for either, e.g., "XTerm*vt100.NAME".

activeIcon (\fPclass\fB ActiveIcon)

        Specifies whether or not active icon windows are to be used when the xterm window is iconified, if this feature is compiled into xterm. The active icon is a miniature representation of the content of the window and will update as the content changes. Not all window managers necessarily support application icon windows. Some window managers will allow you to enter keystrokes into the active icon window. The default is \*(``false.\*(''

allowC1Printable (\fPclass\fB AllowC1Printable)

        If true, overrides the mapping of C1 controls (codes 128-159) to make them be treated as if they were printable characters. Although this corresponds to no particular standard, some users insist it is a VT100. The default is \*(``false.\*(''

allowColorOps (\fPclass\fB AllowColorOps)

    Specifies whether control sequences that set/query the dynamic colors should be allowed. ANSI colors are unaffected by this resource setting. The default is \*(``true.\*(''

allowFontOps (\fPclass\fB AllowFontOps)

    Specifies whether control sequences that set/query the font should be allowed. The default is \*(``false.\*(''

allowScrollLock (\fPclass\fB AllowScrollLock)

        Specifies whether control sequences that set/query the Scroll Lock key should be allowed, as well as whether the Scroll Lock key responds to user's keypress. The default is \*(``false.\*(''

When this feature is enabled, xterm will sense the state of the Scroll Lock key each time it acquires focus. Pressing the Scroll Lock key toggles xterm's internal state, as well as toggling the associated LED. While the Scroll Lock is active, xterm attempts to keep a viewport on the same set of lines. If the current viewport is scrolled past the limit set by the saveLines resource, then Scroll Lock has no further effect.

The reason for setting the default to \*(``false.\*('' is to avoid user surprise. This key is generally unused in keyboard configurations, and has not acquired a standard meaning even when it is used in that manner. Consequently, users have assigned it for ad hoc purposes.

allowSendEvents (\fPclass\fB AllowSendEvents)

        Specifies whether or not synthetic key and button events (generated using the X protocol SendEvent request) should be interpreted or discarded. The default is \*(``false\*('' meaning they are discarded. Note that allowing such events would create a very large security hole, therefore enabling this resource forcefully disables the allowXXXOps resources. The default is \*(``false.\*(''

allowTcapOps (\fPclass\fB AllowTcapOps)

    Specifies whether control sequences that query the terminal's notion of its function-key strings, as termcap or terminfo capabilities should be allowed. The default is \*(``false.\*(''

A few programs, e.g,. vim, use this feature to get an accurate description of the terminal's capabilities, independent of the termcap/terminfo setting:

• -
     xterm can tell the querying program how many colors it supports. This is a constant, depending on how it is compiled, typically 16. It does not change if you alter resource settings, e.g., the boldColors resource.
• -
     xterm can tell the querying program what strings are sent by modified (shift-, control-, alt-) function- and keypad-keys. Reporting control- and alt-modifiers is a feature that relies on the ncurses extended naming.

allowTitleOps (\fPclass\fB AllowTitleOps)

    Specifies whether control sequences that modify the window title or icon name should be allowed. The default is \*(``true.\*(''

allowWindowOps (\fPclass\fB AllowWindowOps)

    Specifies whether extended window control sequences (as used in dtterm) should be allowed. These include several control sequences which manipulate the window size or position, as well as reporting these values and the title or icon name. Each of these can be abused in a script; curiously enough most terminal emulators that implement these restrict only a small part of the repertoire. For fine-tuning, see disallowedWindowOps. The default is \*(``false.\*(''

altIsNotMeta (\fPclass AltIsNotMeta)

        If \*(``true\*('', treat the Alt-key as if it were the Meta-key. Your keyboard may happen to be configured so they are the same. But if they are not, this allows you to use the same prefix- and shifting operations with the Alt-key as with the Meta-key. See altSendsEscape and metaSendsEscape. The default is \*(``false.\*(''

altSendsEscape (\fPclass AltSendsEscape)

        This is an additional keyboard operation that may be processed after the logic for metaSendsEscape. It is only available if the altIsNotMeta resource is set.

If \*(``true\*('', Alt characters (a character combined with the modifier associated with left/right Alt-keys) are converted into a two-character sequence with the character itself preceded by ESC. This applies as well to function key control sequences, unless xterm sees that Alt is used in your key translations. If \*(``false\*('', Alt characters input from the keyboard cause a shift to 8-bit characters (just like metaSendsEscape). By combining the Alt- and Meta-modifiers, you can create corresponding combinations of ESC-prefix and 8-bit characters. The default is \*(``false.\*(''

alwaysBoldMode (\fPclass\fB AlwaysBoldMode)

        Specifies whether xterm should check if the normal and bold fonts are distinct before deciding whether to use overstriking to simulate bold fonts. If this resource is true, xterm does not make the check for distinct fonts when deciding how to handle the boldMode resource. The default is \*(``false.\*(''

alwaysHighlight (\fPclass\fB AlwaysHighlight)

        Specifies whether or not xterm should always display a highlighted text cursor. By default (if this resource is false), a hollow text cursor is displayed whenever the pointer moves out of the window or the window loses the input focus. The default is \*(``false.\*(''

alwaysUseMods (\fPclass\fB AlwaysUseMods)

        Override the numLock resource, telling xterm to use the Alt and Meta modifiers to construct parameters for function key sequences even if those modifiers appear in the translations resource. Normally xterm checks if Alt or Meta is used in a translation that would conflict with function key modifiers, and will ignore these modifiers in that special case. The default is \*(``false.\*(''

answerbackString (\fPclass\fB AnswerbackString)

        Specifies the string that xterm sends in response to an ENQ (control/E) character from the host. The default is a blank string, i.e., \*(``\*(''. A hardware VT100 implements this feature as a setup option.

appcursorDefault (\fPclass\fB AppcursorDefault)

        If \*(``true,\*('' the cursor keys are initially in application mode. This is the same as the VT102 private DECCKM mode, The default is \*(``false.\*(''

appkeypadDefault (\fPclass\fB AppkeypadDefault)

        If \*(``true,\*('' the keypad keys are initially in application mode. The default is \*(``false.\*(''

autoWrap (\fPclass\fB AutoWrap)

        Specifies whether or not auto-wraparound should be enabled. This is the same as the VT102 DECAWM. The default is \*(``true.\*(''

awaitInput (\fPclass\fB AwaitInput)

        Specifies whether or not the xterm uses a 50 millisecond timeout to await input (i.e., to support the Xaw3d arrow scrollbar). The default is \*(``false.\*(''

backarrowKey (\fPclass\fB BackarrowKey)

        Specifies whether the backarrow key transmits a backspace (8) or delete (127) character. This corresponds to the DECBKM control sequence. The default (backspace) is \*(``true.\*('' Pressing the control key toggles this behavior.

background (\fPclass\fB Background)

        Specifies the color to use for the background of the window. The default is \*(``XtDefaultBackground.\*(''

bellIsUrgent (\fPclass\fB BellIsUrgent)

        Specifies whether to set the Urgency hint for the window manager when making a bell sound. The default is \*(``false.\*(''

bellOnReset (\fPclass\fB BellOnReset)

        Specifies whether to sound a bell when doing a hard reset. The default is \*(``true.\*(''

bellSuppressTime (\fPclass\fB BellSuppressTime)

        Number of milliseconds after a bell command is sent during which additional bells will be suppressed. Default is 200. If set non-zero, additional bells will also be suppressed until the server reports that processing of the first bell has been completed; this feature is most useful with the visible bell.

boldColors (\fPclass\fB ColorMode)

        Specifies whether to combine bold attribute with colors like the IBM PC, i.e., map colors 0 through 7 to colors 8 through 15. These normally are the brighter versions of the first 8 colors, hence bold. The default is \*(``true.\*(''

boldFont (\fPclass\fB BoldFont)

        Specifies the name of the bold font to use instead of overstriking. There is no default for this resource.

This font must be the same height and width as the normal font, otherwise it is ignored. If only one of the normal or bold fonts is specified, it will be used as the normal font and the bold font will be produced by overstriking this font.

See also the discussion of boldMode and alwaysBoldMode resources.

boldMode (\fPclass\fB BoldMode)

        This specifies whether or not text with the bold attribute should be overstruck to simulate bold fonts if the resolved bold font is the same as the normal font. It may be desirable to disable bold fonts when color is being used for the bold attribute.

Note that xterm has one bold font which you may set explicitly. Xterm attempts to derive a bold font for the other font selections (font1 through font6). If it cannot find a bold font, it will use the normal font. In each case (whether the explicit resource or the derived font), if the normal and bold fonts are distinct, this resource has no effect. The default is \*(``true.\*(''

See the alwaysBoldMode resource which can modify the behavior of this resource.

Although xterm attempts to derive a bold font for other font selections, the font server may not cooperate. Since X11R6, bitmap fonts have been scaled. The font server claims to provide the bold font that xterm requests, but the result is not always readable. XFree86 provides a feature which can be used to suppress the scaling. In the X server's configuration file (e.g., "/etc/X11/XFree86"), you can add ":unscaled" to the end of the directory specification for the "misc" fonts, which comprise the fixed-pitch fonts that are used by xterm. For example FontPath "/usr/lib/X11/fonts/misc/"

would become FontPath "/usr/lib/X11/fonts/misc/:unscaled"

Depending on your configuration, the font server may have its own configuration file. The same ":unscaled" can be added to its configuration file at the end of the directory specification for "misc".

The bitmap scaling feature is also used by xterm to implement VT102 double-width and double-height characters.

brokenLinuxOSC (\fPclass\fB BrokenLinuxOSC)

        If true, xterm applies a workaround to ignore malformed control sequences that a Linux script might send. Compare the palette control sequences documented in console_codes with ECMA-48. The default is \*(``true.\*(''

brokenSelections (\fPclass\fB BrokenSelections)

        If true, xterm in 8-bit mode will interpret

STRING selections as carrying text in the current locale's encoding. Normally

STRING selections carry ISO-8859-1 encoded text. Setting this resource to \*(``true\*('' violates the ICCCM; it may, however, be useful for interacting with some broken X clients. The default is \*(``false.\*(''

brokenStringTerm (\fPclass\fB BrokenStringTerm)

        provides a work-around for some ISDN routers which start an application control string without completing it. Set this to \*(``true\*('' if xterm appears to freeze when connecting. The default is \*(``false.\*(''

Xterm's state parser recognizes several types of control strings which can contain text, e.g.,

APC (Application Program Command),
DCS (Device Control String),
OSC (Operating System Command),
PM (Privacy Message), and
SOS (Start of String),

Each should end with a string-terminator (a special character which cannot appear in these strings). Ordinary control characters found within the string are not ignored; they are processed without interfering with the process of accumulating the control string's content. Xterm recognizes these controls in all modes, although some of the functions may be suppressed after parsing the control.

When enabled, this feature allows the user to exit from an unterminated control string when any of these ordinary control characters are found:

control/D (used as an end of file in many shells),
control/H (backspace),
control/I (tab-feed),
control/J (line feed aka newline),
control/K (vertical tab),
control/L (form feed),
control/M (carriage return),
control/N (shift-out),
control/O (shift-in),
control/Q (XOFF),
control/X (cancel)

c132 (\fPclass\fB C132)

        Specifies whether or not the VT102 DECCOLM escape sequence, used to switch between 80 and 132 columns, should be honored. The default is \*(``false.\*(''

cacheDoublesize (\fPclass\fB CacheDoublesize)

        Tells whether to cache double-sized fonts by xterm. Set this to zero to disable double-sized fonts altogether.

charClass (\fPclass\fB CharClass)

        Specifies comma-separated lists of character class bindings of the form [low-]high:value. These are used in determining which sets of characters should be treated the same when doing cut and paste. See the CHARACTER CLASSES section.

cjkWidth (\fPclass\fB CjkWidth)

        Specifies whether xterm should follow the traditional East Asian width convention. When turned on, characters with East Asian Ambiguous (A) category in UTR 11 have a column width of 2. You may have to set this option to \*(``true\*('' if you have some old East Asian terminal based programs that assume that line-drawing characters have a column width of 2. If this resource is false, the mkWidth resource controls the choice between the system's wcwidth and xterm's built-in tables. The default is \*(``false.\*(''

color0 (\fPclass\fB Color0)

color1 (\fPclass\fB Color1)

color2 (\fPclass\fB Color2)

color3 (\fPclass\fB Color3)

color4 (\fPclass\fB Color4)

color5 (\fPclass\fB Color5)

color6 (\fPclass\fB Color6)

color7 (\fPclass\fB Color7)

        These specify the colors for the ISO-6429 extension. The defaults are, respectively, black, red3, green3, yellow3, a customizable dark blue, magenta3, cyan3, and gray90. The default shades of color are chosen to allow the colors 8-15 to be used as brighter versions.

color8 (\fPclass\fB Color8)

color9 (\fPclass\fB Color9)

color10 (\fPclass\fB Color10)

color11 (\fPclass\fB Color11)

color12 (\fPclass\fB Color12)

color13 (\fPclass\fB Color13)

color14 (\fPclass\fB Color14)

color15 (\fPclass\fB Color15)

        These specify the colors for the ISO-6429 extension if the bold attribute is also enabled. The default resource values are respectively, gray30, red, green, yellow, a customizable light blue, magenta, cyan, and white.

color16 (\fPclass\fB Color16)

• through

color255 (\fPclass\fB Color255)

        These specify the colors for the 256-color extension. The default resource values are for colors 16 through 231 to make a 6x6x6 color cube, and colors 232 through 255 to make a grayscale ramp.

Resources past color15 are available as a compile-time option. Due to a hardcoded limit in the X libraries on the total number of resources (to 400), the resources for 256-colors are omitted when wide-character support and luit are enabled. Besides inconsistent behavior if only part of the resources were allowed, determining the exact cutoff is difficult, and the X libraries tend to crash if the number of resources exceeds the limit. The color palette is still initialized to the same default values, and can be modified via control sequences.

On the other hand, the resource limit does permit including the entire range for 88-colors.

colorAttrMode (\fPclass\fB ColorAttrMode)

        Specifies whether colorBD, colorBL, colorRV, and colorUL should override ANSI colors. If not, these are displayed only when no ANSI colors have been set for the corresponding position. The default is \*(``false.\*(''

colorBD (\fPclass\fB ColorBD)

        This specifies the color to use to display bold characters if the \*(``colorBDMode\*('' resource is enabled. The default is \*(``XtDefaultForeground.\*(''

colorBDMode (\fPclass\fB ColorAttrMode)

        Specifies whether characters with the bold attribute should be displayed in color or as bold characters. Note that setting colorMode off disables all colors, including bold. The default is \*(``false.\*(''

colorBL (\fPclass\fB ColorBL)

        This specifies the color to use to display blink characters if the \*(``colorBLMode\*('' resource is enabled. The default is \*(``XtDefaultForeground.\*(''

colorBLMode (\fPclass\fB ColorAttrMode)

        Specifies whether characters with the blink attribute should be displayed in color. Note that setting colorMode off disables all colors, including this. The default is \*(``false.\*(''

colorMode (\fPclass\fB ColorMode)

        Specifies whether or not recognition of ANSI (ISO-6429) color change escape sequences should be enabled. The default is \*(``true.\*(''

colorRV (\fPclass\fB ColorRV)

        This specifies the color to use to display reverse characters if the \*(``colorRVMode\*('' resource is enabled. The default is \*(``XtDefaultForeground.\*(''

colorRVMode (\fPclass\fB ColorAttrMode)

        Specifies whether characters with the reverse attribute should be displayed in color. Note that setting colorMode off disables all colors, including this. The default is \*(``false.\*(''

colorUL (\fPclass\fB ColorUL)

        This specifies the color to use to display underlined characters if the \*(``colorULMode\*('' resource is enabled. The default is \*(``XtDefaultForeground.\*(''

colorULMode (\fPclass\fB ColorAttrMode)

        Specifies whether characters with the underline attribute should be displayed in color or as underlined characters. Note that setting colorMode off disables all colors, including underlining. The default is \*(``false.\*(''

combiningChars (\fPclass\fB CombiningChars)

        Specifies the number of wide-characters which can be stored in a cell to overstrike (combine) with the base character of the cell. This can be set to values in the range 0 to 4. The default is \*(``2\*(''.

ctrlFKeys (\fPclass\fB CtrlFKeys)

        In VT220 keyboard mode (see sunKeyboard resource), specifies the amount by which to shift F1-F12 given a control modifier (CTRL). This allows you to generate key symbols for F10-F20 on a Sun/PC keyboard. The default is \*(``10\*('', which means that CTRL F1 generates the key symbol for F11.

curses (\fPclass\fB Curses)

        Specifies whether or not the last column bug in more (1) should be worked around. See the -cu option for details. The default is \*(``false.\*(''

cursorBlink (\fPclass\fB CursorBlink)

        Specifies whether to make the cursor blink. The default is \*(``false.\*(''

cursorColor (\fPclass\fB CursorColor)

        Specifies the color to use for the text cursor. The default is \*(``XtDefaultForeground.\*('' By default, xterm attempts to keep this color from being the same as the background color, since it draws the cursor by filling the background of a text cell. The same restriction applies to control sequences which may change this color.

Setting this resource overrides most of xterm's adjustments to cursor color. It will still use reverse-video to disallow some cases, such as a black cursor on a black background.

cursorOffTime (\fPclass\fB CursorOffTime)

        Specifies the duration of the "off" part of the cursor blink cycle-time in milliseconds. The same timer is used for text blinking. The default is 300.

cursorOnTime (\fPclass\fB CursorOnTime)

        Specifies the duration of the "on" part of the cursor blink cycle-time, in milliseconds. The same timer is used for text blinking. The default is 600.

cutNewline (\fPclass\fB CutNewline)

        If \*(``false\*('', triple clicking to select a line does not include the Newline at the end of the line. If \*(``true\*('', the Newline is selected. The default is \*(``true.\*(''

cursorUnderLine (\fPclass\fB CursorUnderLine)

        Specifies whether to make the cursor underlined or a box. The default is \*(``false.\*(''

cutToBeginningOfLine (\fPclass\fB CutToBeginningOfLine)

        If \*(``false\*('', triple clicking to select a line selects only from the current word forward. If \*(``true\*('', the entire line is selected. The default is \*(``true.\*(''

decTerminalID (\fPclass\fB DecTerminalID)

        Specifies the emulation level (100=VT100, 220=VT220, etc.), used to determine the type of response to a DA control sequence. Leading non-digit characters are ignored, e.g., "vt100" and "100" are the same. The default is 100.

defaultString (\fPclass\fB DefaultString)

        Specify the character (or string) which xterm will substitute when pasted text includes a character which cannot be represented in the current encoding. For instance, pasting UTF-8 text into a display of ISO-8859-1 characters will only be able to display codes 0-255, while UTF-8 text can include Unicode values above 255. The default is \*(``#\*('' (a single pound sign).

If the undisplayable text would be double-width, xterm will add a space after the \*(``#\*('' character, to give roughly the same layout on the screen as the original text.

deleteIsDEL (\fPclass\fB DeleteIsDEL)

        Specifies whether the Delete key on the editing keypad should send DEL (127) or the VT220-style Remove escape sequence. The default is \*(``false,\*('' for the latter.

disallowedColorOps (\fPclass\fB DisallowedColorOps)

        Specify which features will be disabled if allowColorOps is false. This is a comma-separated list of names. The default value is SetColor,GetColor,GetAnsiColor

The names are listed below. xterm ignores capitalization, but they are shown in mixed-case for clarity.

• SetColor
       Set a specific dynamic color.
• GetColor
       Report the current setting of a given dynamic color.
• GetAnsiColor
       Report the current setting of a given ANSI color (actually any of the colors set via ANSI-style controls).

disallowedFontOps (\fPclass\fB DisallowedFontOps)

        Specify which features will be disabled if allowFontOps is false. This is a comma-separated list of names. The default value is SetFont,GetFont

The names are listed below. xterm ignores capitalization, but they are shown in mixed-case for clarity.

• SetFont
       Set the specified font.
• GetFont
       Report the specified font.

disallowedTcapOps (\fPclass\fB DisallowedTcapOps)

        Specify which features will be disabled if allowTcapOps is false. This is a comma-separated list of names. The default value is SetTcap,GetTcap

The names are listed below. xterm ignores capitalization, but they are shown in mixed-case for clarity.

• SetTcap
       (not implemented)
• GetTcap
       Report specified function- and other special keys.

disallowedWindowOps (\fPclass\fB DisallowedWindowOps)

        Specify which features will be disabled if allowWindowOps is false. This is a comma-separated list of names, or (for the controls adapted from dtterm the operation number). The default value is 1,2,3,4,5,6,7,8,9,11,13,14,18,19,20,21,GetSelection,SetSelection,SetWinLines,SetXprop (i.e. no operations are allowed).

The names are listed below. xterm ignores capitalization, but they are shown in mixed-case for clarity. Where a number can be used as an alternative, it is given in parentheses after the name.

• GetIconTitle (20)
       Report xterm window's icon label as a string.
• GetScreenSizeChars (19)
       Report the size of the screen in characters as numbers.
• GetSelection
       Report selection data as a base64 string.

       Resize the text area to given size in characters.
• SetWinSizePixels (4)
       Resize the xterm window to given size in pixels.
• SetXprop
       Set X property on top-level window.

dynamicColors (\fPclass\fB DynamicColors)

        Specifies whether or not escape sequences to change colors assigned to different attributes are recognized.

eightBitControl (\fPclass EightBitControl)

        Specifies whether or not control sequences sent by the terminal should be eight-bit characters or escape sequences. The default is \*(``false.\*(''

eightBitInput (\fPclass EightBitInput)

        If \*(``true\*('', Meta characters (a single-byte character combined with the Meta modifier key) input from the keyboard are presented as a single character with the eighth bit turned on. The terminal is put into 8-bit mode. If \*(``false\*('', Meta characters are converted into a two-character sequence with the character itself preceded by ESC. On startup, xterm tries to put the terminal into 7-bit mode. The metaSendsEscape and altSendsEscape resources may override this. The default is \*(``true.\*(''

Generally keyboards do not have a key labeled "Meta", but "Alt" keys are common, and they are conventionally used for "Meta". If they were synonymous, it would have been reasonable to name this resource "altSendsEscape", reversing its sense. For more background on this, see the meta function in curses.

Note that the Alt key is not necessarily the same as the Meta modifier. xmodmap lists your key modifiers. X defines modifiers for shift, (caps) lock and control, as well as 5 additional modifiers which are generally used to configure key modifiers. xterm inspects the same information to find the modifier associated with either Meta key (left or right), and uses that key as the Meta modifier. It also looks for the NumLock key, to recognize the modifier which is associated with that.

If your xmodmap configuration uses the same keycodes for Alt- and Meta-keys, xterm will only see the Alt-key definitions, since those are tested before Meta-keys. NumLock is tested first. It is important to keep these keys distinct; otherwise some of xterm's functionality is not available.

eightBitOutput (\fPclass EightBitOutput)

        Specifies whether or not eight-bit characters sent from the host should be accepted as is or stripped when printed. The default is \*(``true,\*('' which means that they are accepted as is.

eightBitSelectTypes (\fPclass EightBitSelectTypes)

        Override xterm's default selection target list (see SELECT/PASTE) for selections in normal (ISO-8859-1) mode. The default is an empty string, which does not override anything.

faceName (\fPclass\fB FaceName)

        Specify the pattern for fonts selected from the FreeType library if support for that library was compiled into xterm. There is no default value.

If not specified, or if there is no match for both normal and bold fonts, xterm\fR uses the \fBfont and related resources.

faceNameDoublesize (\fPclass\fB FaceNameDoublesize)

        Specify an double-width font for cases where an application requires this, e.g., in CJK applications. There is no default value.

If the application uses double-wide characters and this resource is not given, xterm will use a scaled version of the font given by faceName.

faceSize (\fPclass\fB FaceSize)

        Specify the pointsize for fonts selected from the FreeType library if support for that library was compiled into xterm. The default is \*(``14.\*('' On the VT Fonts menu, this corresponds to the Default entry.

Although the default is \*(``14.\*('', this may not be the same as the pointsize for the default bitmap font, i.e., that assigned with the -fn option, or the font resource. For example, the "fixed" font usually has a pointsize of \*(``8.\*(''. If you set faceSize to match the size of the bitmap font, then switching between bitmap and TrueType fonts via the font menu will give comparable sizes for the window.

You can specify the pointsize for TrueType fonts selected with the other size-related menu entries such as Medium, Huge, etc., by using one of the following resource values. If you do not specify a value, they default to \*(``0.0\*('', which causes xterm to use the ratio of font sizes from the corresponding bitmap font resources to obtain a TrueType pointsize.

If all of the faceSize resources are set, then xterm will use this information to determine the next smaller/larger TrueType font for the larger-vt-font() and smaller-vt-font() actions. If any are not set, xterm will use only the areas of the bitmap fonts.

faceSize1 (\fPclass\fB FaceSize1)

        Specifies the pointsize of the first alternative font.

faceSize2 (\fPclass\fB FaceSize2)

        Specifies the pointsize of the second alternative font.

faceSize3 (\fPclass\fB FaceSize3)

        Specifies the pointsize of the third alternative font.

faceSize4 (\fPclass\fB FaceSize4)

        Specifies the pointsize of the fourth alternative font.

faceSize5 (\fPclass\fB FaceSize5)

        Specifies the pointsize of the fifth alternative font.

faceSize6 (\fPclass\fB FaceSize6)

        Specifies the pointsize of the sixth alternative font.

font (\fPclass\fB Font)

        Specifies the name of the normal font. The default is \*(``fixed.\*(''

See the discussion of the locale resource, which describes how this font may be overridden.

NOTE: some resource files use patterns such as *font: fixed

which are overly broad, affecting both xterm.vt100.font

and xterm.vt100.utf8fonts.font

which is probably not what you intended.

fastScroll (\fPclass\fB FastScroll)

        Modifies the effect of jump scroll (jumpScroll) by suppressing screen refreshes for the special case when output to the screen has completely shifted the contents off-screen. For instance, cat'ing a large file to the screen does this.

font1 (\fPclass\fB Font1)

        Specifies the name of the first alternative font.

font2 (\fPclass\fB Font2)

        Specifies the name of the second alternative font.

font3 (\fPclass\fB Font3)

        Specifies the name of the third alternative font.

font4 (\fPclass\fB Font4)

        Specifies the name of the fourth alternative font.

font5 (\fPclass\fB Font5)

        Specifies the name of the fifth alternative font.

font6 (\fPclass\fB Font6)

        Specifies the name of the sixth alternative font.

fontDoublesize (\fPclass\fB FontDoublesize)

        Specifies whether xterm should attempt to use font scaling to draw double-sized characters. Some older font servers cannot do this properly, will return misleading font metrics. The default is \*(``true\*(''. If disabled, xterm will simulate double-sized characters by drawing normal characters with spaces between them.

fontWarnings (\fPclass\fB FontWarnings)

        Specify whether xterm should report an error if it fails to load a font:

• 0
       Never report an error (though the X libraries may).
• 1
       Report an error if the font name was given as a resource setting.
• 2
       Always report an error on failure to load a font.

forceBoxChars (\fPclass\fB ForceBoxChars)

        Specifies whether xterm should assume the normal and bold fonts have VT100 line-drawing characters:

• -
       The fixed-pitch ISO-8859-*-encoded fonts used by xterm normally have the VT100 line-drawing glyphs in cells 1-31. Other fixed-pitch fonts may be more attractive, but lack these glyphs.
• -
      When using an ISO-10646-1 font and the wideChars resource is true, xterm uses the Unicode glyphs which match the VT100 line-drawing glyphs.

If \*(``false\*('', xterm checks for missing glyphs in the font and makes line-drawing characters directly as needed. If \*(``true\*('', xterm assumes the font does not contain the line-drawing characters, and draws them directly. The default is \*(``false.\*(''

forcePackedFont (\fPclass\fB ForcePackedFont)

        Specifies whether xterm should use the maximum or minimum glyph width when displaying using a bitmap font. Use the maximum width to help with proportional fonts. The default is \*(``true,\*('' denoting the minimum width.

foreground (\fPclass\fB Foreground)

        Specifies the color to use for displaying text in the window. Setting the class name instead of the instance name is an easy way to have everything that would normally appear in the text color change color. The default is \*(``XtDefaultForeground.\*(''

formatOtherKeys (\fPclass\fB FormatOtherKeys)

        Overrides the format of the escape sequence used to report modified keys with the modifyOtherKeys resource.

• 0
     send modified keys as parameters for function-key 27 (default).
• 1
     send modified keys as parameters for CSI u.

freeBoldBox (\fPclass\fB FreeBoldBox)

        Specifies whether xterm should assume the bounding boxes for normal and bold fonts are compatible. If \*(``false\*('', xterm compares them and will reject choices of bold fonts that do not match the size of the normal font. The default is \*(``false\*('', which means that the comparison is performed.

geometry (\fPclass\fB Geometry)

        Specifies the preferred size and position of the VT102 window. There is no default for this resource.

highlightColor (\fPclass\fB HighlightColor)

        Specifies the color to use for the background of selected (highlighted) text. If not specified (i.e., matching the default foreground), reverse video is used. The default is \*(``XtDefaultForeground.\*(''

highlightColorMode (\fPclass\fB HighlightColorMode)

        Specifies whether xterm should use highlightTextColor and highlightColor to override the reversed foreground/background colors in a selection. The default is unspecified: at startup, xterm checks if those resources are set to something other than the default foreground and background colors. Setting this resource disables the check.

The following table shows the interaction of the highlighting resources, abbreviated as shown to fit in this page:

• HCM
     highlightColorMode
• HR
     highlightReverse
• HBG
     highlightColor
• HFG
     highlightTextColor

highlightReverse (\fPclass\fB HighlightReverse)

        Specifies whether xterm should reverse the selection foreground and background colors when selecting text with reverse-video attribute. This applies only to the highlightColor and highlightTextColor resources, e.g., to match the color scheme of xwsh. If \*(``true\*('', xterm reverses the colors, If \*(``false\*('', xterm does not reverse colors, The default is \*(``true.\*(''

highlightSelection (\fPclass\fB HighlightSelection)

        If \*(``false\*('', selecting with the mouse highlights all positions on the screen between the beginning of the selection and the current position. If \*(``true\*('', xterm highlights only the positions that contain text that can be selected. The default is \*(``false.\*(''

Depending on the way your applications write to the screen, there may be trailing blanks on a line. Xterm stores data as it is shown on the screen. Erasing the display changes the internal state of each cell so it is not considered a blank for the purpose of selection. Blanks written since the last erase are selectable. If you do not wish to have trailing blanks in a selection, use the trimSelection resource.

highlightTextColor (\fPclass\fB HighlightTextColor)

        Specifies the color to use for the foreground of selected (highlighted) text. If not specified (i.e., matching the default background), reverse video is used. The default is \*(``XtDefaultBackground.\*(''

hpLowerleftBugCompat (\fPclass\fB HpLowerleftBugCompat)

        Specifies whether to work around a bug in HP's xdb, which ignores termcap and always sends ESC F to move to the lower left corner. \*(``true\*('' causes xterm to interpret ESC F as a request to move to the lower left corner of the screen. The default is \*(``false.\*(''

i18nSelections (\fPclass\fB I18nSelections)

        If false, xterm will not request the targets

COMPOUND_TEXT or

R TEXT . The default is \*(``true.\*('' It may be set to false in order to work around ICCCM violations by other X clients.

iconBorderColor (\fPclass\fB BorderColor)

        Specifies the border color for the active icon window if this feature is compiled into xterm. Not all window managers will make the icon border visible.

iconBorderWidth (\fPclass\fB BorderWidth)

        Specifies the border width for the active icon window if this feature is compiled into xterm. The default is 2. Not all window managers will make the border visible.

iconFont (\fPclass\fB IconFont)

        Specifies the font for the miniature active icon window, if this feature is compiled into xterm. The default is "nil2".

initialFont (\fPclass\fB InitialFont)

        Specifies which of the VT100 fonts to use initially. Values are the same as for the set-vt-font action. The default is \*(``d\*('', i.e., "default".

inputMethod (\fPclass\fB XtCInputMethod)

        Tells xterm which type of input method to use. There is no default method.

internalBorder (\fPclass\fB BorderWidth)

        Specifies the number of pixels between the characters and the window border. The default is 2.

italicULMode (\fPclass\fB ColorAttrMode)

        Specifies whether characters with the underline attribute should be displayed in an italic font or as underlined characters. It is implemented only for TrueType fonts.

jumpScroll (\fPclass\fB JumpScroll)

        Specifies whether or not jump scroll should be used. This corresponds to the VT102 DECSCLM private mode. The default is \*(``true.\*('' See fastScroll for a variation.

keepSelection (\fPclass\fB KeepSelection)

        Specifies whether xterm will keep the selection even after the selected area was touched by some output to the terminal. The default is \*(``true\*(''.

keyboardDialect (\fPclass\fB KeyboardDialect)

        Specifies the initial keyboard dialect, as well as the default value when the terminal is reset. The value given is the same as the final character in the control sequences which change character sets. The default is \*(``B\*('', which corresponds to US ASCII.

nameKeymap (class\fB NameKeymap)
        See the discussion of the keymap() action.

limitResize (\fPclass\fB LimitResize)

        Limits resizing of the screen via control sequence to a given multiple of the display dimensions. The default is \*(``1\*(''.

locale (\fPclass\fB Locale)

        Specifies how to use luit, an encoding converter between UTF-8 and locale encodings. The resource value (ignoring case) may be:

• true
      xterm will use the encoding specified by the users' LC_CTYPE locale (i.e., LC_ALL, LC_CTYPE, or LANG variables) as far as possible. This is realized by always enabling UTF-8 mode and invoking luit in non-UTF-8 locales.
• medium
      xterm will follow users' LC_CTYPE locale only for UTF-8, east Asian, and Thai locales, where the encodings were not supported by conventional 8bit mode with changing fonts. For other locales, xterm will use conventional 8bit mode.
• checkfont
      If mini-luit is compiled-in, xterm will check if a Unicode font has been specified. If so, it checks if the character encoding for the current locale is POSIX, Latin-1 or Latin-9, uses the appropriate mapping to support those with the Unicode font. For other encodings, xterm assumes that UTF-8 encoding is required.
• false
      xterm will use conventional 8bit mode or UTF-8 mode according to utf8\fR resource or \fB-u8 option.

Any other value, e.g., \*(``UTF-8\*('' or \*(``ISO8859-2\*('', is assumed to be an encoding name; luit will be invoked to support the encoding. The actual list of supported encodings depends on luit. The default is \*(``medium\*(''.

Regardless of your locale and encoding, you need an ISO-10646-1 font to display the result. Your configuration may not include this font, or locale-support by xterm may not be needed. At startup, xterm uses a mechanism equivalent to the load-vt-fonts(utf8Fonts, Utf8Fonts) action to load font name subresources of the VT100 widget. That is, resource patterns such as "*vt100.utf8Fonts.font" will be loaded, and (if this resource is enabled), override the normal fonts. If no subresources are found, the normal fonts such as "*vt100.font", etc., are used. The resource files distributed with xterm use ISO-10646-1 fonts, but do not rely on them unless you are using the locale mechanism.

localeFilter (\fPclass\fB LocaleFilter)

        Specifies the file name for the encoding converter from/to locale encodings and UTF-8 which is used with the -lc option or locale resource. The help message shown by \*(``xterm -help\*('' lists the default value, which depends on your system configuration.

If the encoding converter requires command-line parameters, you should put those within a shell script to execute the converter, and set this resource to point to the shell script.

loginShell (\fPclass\fB LoginShell)

        Specifies whether or not the shell to be run in the window should be started as a login shell. The default is \*(``false.\*(''

marginBell (\fPclass\fB MarginBell)

        Specifies whether or not the bell should be rung when the user types near the right margin. The default is \*(``false.\*(''

metaSendsEscape (\fPclass MetaSendsEscape)

        If \*(``true\*('', Meta characters (a character combined with the Meta modifier key) are converted into a two-character sequence with the character itself preceded by ESC. This applies as well to function key control sequences, unless xterm sees that Meta is used in your key translations. If \*(``false\*('', Meta characters input from the keyboard are handled according to the eightBitInput resource. The default is \*(``false.\*(''

mkSamplePass (\fPclass\fB MkSamplePass)

        If mkSampleSize is nonzero, and mkWidth (and cjkWidth) are false, on startup xterm compares its built-in tables to the system's wide character width data to decide if it will use the system's data. It tests the first mkSampleSize character values, and allows up to mkSamplePass mismatches before the test fails. The default (for the allowed number of mismatches) is 256.

mkSampleSize (\fPclass\fB MkSampleSize)

        With mkSamplePass, this specifies a startup test used for initializing wide character width calculations. The default (number of characters to check) is 1024.

mkWidth (\fPclass\fB MkWidth)

        Specifies whether xterm should use a built-in version of the wide character width calculation. See also the cjkWidth resource which can override this. The default is \*(``false.\*(''

Here is a summary of the resources which control the choice of wide character width calculation:

modifyCursorKeys (\fPclass ModifyCursorKeys)

        Tells how to handle the special case where Control-, Shift-, Alt- or Meta-modifiers are used to add a parameter to the escape sequence returned by a cursor-key. The default is \*(``2\*('':

Set it to -1 to disable it.
Set it to 0 to use the old/obsolete behavior.
Set it to 1 to prefix modified sequences with CSI.
Set it to 2 to force the modifier to be the second parameter if it would otherwise be the first.
Set it to 3 to mark the sequence with a \*(``>\*('' to hint that it is private.

modifyFunctionKeys (\fPclass ModifyFunctionKeys)

        Tells how to handle the special case where Control-, Shift-, Alt- or Meta-modifiers are used to add a parameter to the escape sequence returned by a (numbered) function-key. The default is \*(``2\*(''. The resource values are similar to modifyCursorKeys:

Set it to -1 to permit the user to use shift- and control-modifiers to construct function-key strings using the normal encoding scheme.
Set it to 0 to use the old/obsolete behavior.
Set it to 1 to prefix modified sequences with CSI.
Set it to 2 to force the modifier to be the second parameter if it would otherwise be the first.
Set it to 3 to mark the sequence with a \*(``>\*('' to hint that it is private.

If modifyFunctionKeys is zero, xterm uses Control- and Shift-modifiers to allow the user to construct numbered function-keys beyond the set provided by the keyboard:

• Control
       adds the value given by the ctrlFKeys resource.
• Shift
       adds twice the value given by the ctrlFKeys resource.
• Control/Shift
       adds three times the value given by the ctrlFKeys resource.

As a special case, legacy (when oldFunctionKeys is true) or vt220 (when sunKeyboard is true) keyboards interpret only the Control-modifier when constructing numbered function-keys. This is done to provide compatible keyboards for DEC VT220 and related terminals that implement user-defined keys (UDK).

modifyOtherKeys (\fPclass ModifyOtherKeys)

        Like modifyCursorKeys, tells xterm to construct an escape sequence for other keys (such as "2") when modified by Control-, Alt- or Meta-modifiers. This feature does not apply to function keys and well-defined keys such as ESC or the control keys. The default is \*(``0\*('':

• 0
       disables this feature.
• 1
       enables this feature for keys except for those with well-known behavior, e.g., Tab, Backarrow and some special control character cases, e.g., Control-Space to make a NUL.
• 2
       enables this feature for keys including the exceptions listed.

multiClickTime (\fPclass\fB MultiClickTime)

        Specifies the maximum time in milliseconds between multi-click select events. The default is 250 milliseconds.

multiScroll (\fPclass\fB MultiScroll)

        Specifies whether or not scrolling should be done asynchronously. The default is \*(``false.\*(''

nMarginBell (\fPclass\fB Column)

        Specifies the number of characters from the right margin at which the margin bell should be rung, when enabled by the marginBell resource. The default is 10.

numLock (\fPclass\fB NumLock)

        If \*(``true\*('', xterm\fR checks if NumLock is used as a modifier (see \fIxmodmap(1)). If so, this modifier is used to simplify the logic when implementing special NumLock for the sunKeyboard resource. Also (when sunKeyboard is false), similar logic is used to find the modifier associated with the left and right Alt keys. The default is \*(``true.\*(''

oldXtermFKeys (\fPclass\fB OldXtermFKeys)

        If \*(``true\*('', xterm will use old-style control sequences for function keys F1 to F4, for compatibility with X Consortium xterm. Otherwise, it uses the VT100-style codes for PF1 to PF4. The default is \*(``false.\*(''

on2Clicks (\fPclass\fB On2Clicks)

on3Clicks (\fPclass\fB On3Clicks)

on4Clicks (\fPclass\fB On4Clicks)

on5Clicks (\fPclass\fB On5Clicks)

    Specify selection behavior in response to multiple mouse clicks. A single mouse click is always interpreted as described in the SELECTION section (see POINTER USAGE). Multiple mouse clicks (using the button which activates the select-start action) are interpreted according to the resource values of on2Clicks, etc. The resource value can be one of these:

• word
     Select a \*(``word\*('' as determined by the charClass resource. See the CHARACTER CLASSES section.
• line
      Select a line (counting wrapping).
• group
      Select a group of adjacent lines (counting wrapping). The selection stops on a blank line, and does not extend outside the current page.
• page
      Select all visible lines, i.e., the page.
• all
      Select all lines, i.e., including the saved lines.
• regex
      Select a \*(``word\*('' as determined by the regular expression which follows in the resource value.
• none
      No selection action is associated with this resource. xterm interprets it as the end of the list. For example, you may use it to disable triple (and higher) clicking by setting on3Clicks to \*(``none\*(''.

The default values for on2Clicks and on3Clicks are \*(``word\*('' and \*(``line\*('', respectively. There is no default value for on4Clicks or on5Clicks, making those inactive. On startup, xterm determines the maximum number of clicks by the onXClicks resource values which are set.

openIm (\fPclass\fB XtCOpenIm)

        Tells xterm whether to open the input method at startup. The default is \*(``true\*(''.

pointerColor (\fPclass\fB PointerColor)

        Specifies the foreground color of the pointer. The default is \*(``XtDefaultForeground.\*(''

pointerColorBackground (\fPclass\fB PointerColorBackground)

        Specifies the background color of the pointer. The default is \*(``XtDefaultBackground.\*(''

pointerMode (\fPclass\fB PointerMode)

        Specifies when the pointer may be hidden as the user types. It will be redisplayed if the user moves the mouse, or clicks one of its buttons.

• 0
     never
• 1
     the application running in xterm has not activated mouse mode. This is the default.
• 2
     always.

pointerShape (\fPclass\fB Cursor)

        Specifies the name of the shape of the pointer. The default is \*(``xterm.\*(''

popOnBell (\fPclass\fB PopOnBell)

        Specifies whether the window would be raised when Control-G is received. The default is \*(``false.\*(''

If the window is iconified, this has no effect. However, the zIconBeep resource provides you with the ability to see which iconified windows have sounded a bell.

preeditType (\fPclass\fB XtCPreeditType)

        Tells xterm which types of preedit (preconversion) string to display. The default is \*(``OverTheSpot,Root\*(''.

printAttributes (\fPclass\fB PrintAttributes)

        Specifies whether to print graphic attributes along with the text. A real DEC VTxxx terminal will print the underline, highlighting codes but your printer may not handle these. A \*(``0\*('' disables the attributes. A \*(``1\*('' prints the normal set of attributes (bold, underline, inverse and blink) as VT100-style control sequences. A \*(``2\*('' prints ANSI color attributes as well. The default is \*(``1.\*(''

printerAutoClose (\fPclass\fB PrinterAutoClose)

        If \*(``true\*('', xterm will close the printer (a pipe) when the application switches the printer offline with a Media Copy command. The default is \*(``false.\*(''

printerCommand (\fPclass\fB PrinterCommand)

        Specifies a shell command to which xtermwill open a pipe when the first MC (Media Copy) command is initiated. The default is a blank string. If the resource value is given as a blank string, the printer is disabled.

printerControlMode (\fPclass\fB PrinterControlMode)

        Specifies the printer control mode. A \*(``1\*('' selects autoprint mode, which causes xtermto print a line from the screen when you move the cursor off that line with a line feed, form feed or vertical tab character, or an autowrap occurs. Autoprint mode is overridden by printer controller mode (a \*(``2\*(''), which causes all of the output to be directed to the printer. The default is \*(``0.\*(''

printerExtent (\fPclass\fB PrinterExtent)

        Controls whether a print page function will print the entire page (true), or only the the portion within the scrolling margins (false). The default is \*(``false.\*(''

printerFormFeed (\fPclass\fB PrinterFormFeed)

        Controls whether a form feed is sent to the printer at the end of a print page function. The default is \*(``false.\*(''

printerNewLine (\fPclass\fB PrinterNewLine)

        Controls whether a newline is sent to the printer at the end of a print page function. The default is \*(``true.\*(''

quietGrab (\fPclass\fB QuietGrab)

        Controls whether the cursor is repainted when NotifyGrab and NotifyUngrab event types are received during change of focus. The default is \*(``false.\*(''

renderFont (\fPclass\fB RenderFont)

        If xterm is built with the Xft library, this controls whether the faceName resource is used. The default is \*(``default.\*(''

The resource values are strings, evaluated as booleans after startup.

• false
       
  disable the feature and use the normal (bitmap) font.
• true
       
  startup using the TrueType font specified by the faceName and faceSize resource settings. If there is no value for faceName, disable the feature and use the normal (bitmap) font.

After startup, you can still switch to/from the bitmap font using the \*(``TrueType Fonts\*('' menu entry.

• default
       
  startup using the normal (bitmap) font, but enable the \*(``TrueType Fonts\*('' menu entry to allow runtime switching to/from TrueType fonts.

If there is no faceName resource set, then runtime switching to TrueType fonts is disabled. Xterm has a separate compiled-in value for faceName for the special case where renderFont is \*(``default\*(''. That is normally \*(``mono\*(''.

resizeGravity (\fPclass\fB ResizeGravity)

        Affects the behavior when the window is resized to be taller or shorter. NorthWest specifies that the top line of text on the screen stay fixed. If the window is made shorter, lines are dropped from the bottom; if the window is made taller, blank lines are added at the bottom. This is compatible with the behavior in R4. SouthWest (the default) specifies that the bottom line of text on the screen stay fixed. If the window is made taller, additional saved lines will be scrolled down onto the screen; if the window is made shorter, lines will be scrolled off the top of the screen, and the top saved lines will be dropped.

retryInputMethod (\fPclass\fB XtCRetryInputMethod)

        Tells xterm how many times to retry, in case the input-method server is not responding. This is a different issue than unsupported preedit type, etc. You may encounter retries if your X configuration (and its libraries) are missing pieces. Setting this resource to zero ``0'' will cancel the retrying. The default is ``3''.

reverseVideo (\fPclass\fB ReverseVideo)

        Specifies whether or not reverse video should be simulated. The default is \*(``false.\*(''

reverseWrap (\fPclass\fB ReverseWrap)

        Specifies whether or not reverse-wraparound should be enabled. This corresponds to xterm's private mode 45. The default is \*(``false.\*(''

rightScrollBar (\fPclass\fB RightScrollBar)

        Specifies whether or not the scrollbar should be displayed on the right rather than the left. The default is \*(``false.\*(''

saveLines (\fPclass\fB SaveLines)

        Specifies the number of lines to save beyond the top of the screen when a scrollbar is turned on. The default is 64.

scrollBar (\fPclass\fB ScrollBar)

        Specifies whether or not the scrollbar should be displayed. The default is \*(``false.\*(''

scrollBarBorder (\fPclass\fB ScrollBarBorder)

        Specifies the width of the scrollbar border. Note that this is drawn to overlap the border of the xterm window. Modifying the scrollbar's border affects only the line between the VT100 widget and the scrollbar. The default value is 1.

scrollKey (\fPclass\fB ScrollCond)

        Specifies whether or not pressing a key should automatically cause the scrollbar to go to the bottom of the scrolling region. This corresponds to xterm's private mode 1011. The default is \*(``false.\*(''

scrollLines (\fPclass\fB ScrollLines)

        Specifies the number of lines that the scroll-back and scroll-forw actions should use as a default. The default value is 1.

scrollTtyOutput (\fPclass\fB ScrollCond)

        Specifies whether or not output to the terminal should automatically cause the scrollbar to go to the bottom of the scrolling region. The default is \*(``true.\*(''

selectToClipboard (\fPclass\fB SelectToClipboard)

    Tells xterm whether to use the PRIMARY or CLIPBOARD for SELECT tokens in the selection mechanism. The set-select action can change this at runtime, allowing the user to work with programs that handle only one of these mechanisms. The default is \*(``false\*('', which tells it to use PRIMARY.

shiftFonts (\fPclass\fB ShiftFonts)

        Specifies whether to enable the actions larger-vt-font() and smaller-vt-font(), which are normally bound to the shifted KP_Add and KP_Subtract. The default is \*(``true.\*(''

showBlinkAsBold (\fPclass\fB ShowBlinkAsBold)

        Tells xterm whether to display text with blink-attribute the same as bold. If xterm has not been configured to support blinking text, the default is \*(``true.\*('', which corresponds to older versions of xterm, otherwise the default is \*(``false.\*(''

showMissingGlyphs (\fPclass\fB ShowMissingGlyphs)

        Tells xterm whether to display a box outlining places where a character has been used that the font does not represent. The default is \*(``false.\*(''

signalInhibit (\fPclass\fB SignalInhibit)

        Specifies whether or not the entries in the \*(``Main Options\*('' menu for sending signals to xterm should be disallowed. The default is \*(``false.\*(''

tekGeometry (\fPclass\fB Geometry)

        Specifies the preferred size and position of the Tektronix window. There is no default for this resource.

tekInhibit (\fPclass\fB TekInhibit)

        Specifies whether or not the escape sequence to enter Tektronix mode should be ignored. The default is \*(``false.\*(''

tekSmall (\fPclass\fB TekSmall)

        Specifies whether or not the Tektronix mode window should start in its smallest size if no explicit geometry is given. This is useful when running xterm on displays with small screens. The default is \*(``false.\*(''

tekStartup (\fPclass\fB TekStartup)

        Specifies whether or not xterm should start up in Tektronix mode. The default is \*(``false.\*(''

tiXtraScroll (\fPclass\fB TiXtraScroll)

        Specifies whether xterm should scroll to a new page when processing the ti termcap entry, i.e., the private modes 47, 1047 or 1049. This is only in effect if titeInhibit is \*(``true\*('', because the intent of this option is to provide a picture of the full-screen application's display on the scrollback without wiping out the text that would be shown before the application was initialized. The default for this resource is \*(``false.\*(''

titeInhibit (\fPclass\fB TiteInhibit)

        Specifies whether or not xterm should remove ti and te termcap entries (used to switch between alternate screens on startup of many screen-oriented programs) from the TERMCAP string. If set, xterm also ignores the escape sequence to switch to the alternate screen. Xterm supports terminfo in a different way, supporting composite control sequences (also known as private modes) 1047, 1048 and 1049 which have the same effect as the original 47 control sequence. The default for this resource is \*(``false.\*(''

titleModes (\fPclass\fB TitleModes)

        Tells xterm whether to accept or return window- and icon-labels in ISO-8859-1 (the default) or UTF-8. Either can be encoded in hexadecimal. The default for this resource is \*(``0.\*(''

Each bit (bit "0" is 1, bit "1" is 2, etc) corresponds to one of the parameters set by the title modes control sequence:

• 0
       Set window/icon labels using hexadecimal
• 1
       Query window/icon labels using hexadecimal
• 2
       Set window/icon labels using UTF-8 (overrides utf8Titles resource).
• 3
       Query window/icon labels using UTF-8

translations (\fPclass\fB Translations)

        Specifies the key and button bindings for menus, selections, \*(``programmed strings,\*('' etc. The translations resource, which provides much of xterm's configurability, is a feature of the X Toolkit Intrinsics library (Xt). See the ACTIONS section.

trimSelection (\fPclass\fB TrimSelection)

        If you set highlightSelection, you can see the text which is selected, including any trailing spaces. Clearing the screen (or a line) resets it to a state containing no spaces. Some lines may contain trailing spaces when an application writes them to the screen. However, you may not wish to paste lines with trailing spaces. If this resource is true, xterm will trim trailing spaces from text which is selected. It does not affect spaces which result in a wrapped line, nor will it trim the trailing newline from your selection. The default is \*(``false.\*(''

underLine (\fPclass\fB UnderLine)

        This specifies whether or not text with the underline attribute should be underlined. It may be desirable to disable underlining when color is being used for the underline attribute. The default is \*(``true.\*(''

useClipping (\fPclass\fB UseClipping)

        Tell xterm whether to use clipping to keep from producing dots outside the text drawing area. Originally used to work around for overstriking effects, this is also needed to work with some incorrectly-sized fonts. The default is \*(``true.\*(''

utf8 (\fPclass\fB Utf8)

        This specifies whether xterm will run in UTF-8 mode. If you set this resource, xterm also sets the wideChars resource as a side-effect. The resource is an integer, expected to range from 0 to 3:

• 0
     UTF-8 mode is initially off. The command-line option +u8 sets the resource to this value. Escape sequences for turning UTF-8 mode on/off are allowed.
• 1
      UTF-8 mode is initially on. Escape sequences for turning UTF-8 mode on/off are allowed.
• 2
      The command-line option -u8 sets the resource to this value. Escape sequences for turning UTF-8 mode on/off are ignored.
• 3
      This is the default value of the resource. It is changed during initialization depending on whether the locale resource was set, to 0 or 2. See the locale resource for additional discussion of non-UTF-8 locales.

If you want to set the value of utf8, it should be in this range. Other nonzero values are treated the same as \*(``1\*('', i.e., UTF-8 mode is initially on, and escape sequences for turning UTF-8 mode on/off are allowed.

utf8Fonts (\fPclass\fB Utf8Fonts)

        See the discussion of the locale resource.

utf8Latin1 (\fPclass\fB Utf8Latin1)

        If true, allow an ISO-8859-1 normal font to be combined with an ISO-10646 font if the latter is given via the -fw option or its corresponding resource value. The default is \*(``false.\*(''

utf8SelectTypes (\fPclass\fB Utf8SelectTypes)

        Override xterm's default selection target list (see SELECT/PASTE) for selections in wide-character (UTF-8) mode. The default is an empty string, which does not override anything.

utf8Title (\fPclass\fB Utf8Title)

        Applications can set xterm's title by writing a control sequence. Normally this control sequence follows the VT220 convention, which encodes the string in ISO-8859-1 and allows for an 8-bit string terminator. If xterm is started in a UTF-8 locale, it translates the ISO-8859-1 string to UTF-8 to work with the X libraries which assume the string is UTF-8.

However, some users may wish to write a title string encoded in UTF-8. Set this resource to \*(``true\*('' to allow UTF-8 encoded title strings. That cancels the translation to UTF-8, allowing UTF-8 strings to be displayed as is.

This feature is available as a menu entry, since it is related to the particular applications you are running within xterm. You can also use a control sequence (see the discussion of "Title Modes" in the control sequences document), to set an equivalent flag. The titleModes resource sets the same value, which overrides this resource.

The default is \*(``false.\*(''

veryBoldColors (\fPclass\fB VeryBoldColors)         Specifies whether to combine video attributes with colors specified by colorBD, colorBL, colorRV and colorUL. The resource value is the sum of values for each attribute:           .nf 1 for reverse, 2 for underline, 4 for bold and 8 for blink.

The default is \*(``0.\*(''

visualBell (\fPclass\fB VisualBell)

        Specifies whether or not a visible bell (i.e., flashing) should be used instead of an audible bell when Control-G is received. The default is \*(``false.\*(''

visualBellDelay (\fPclass\fB VisualBellDelay)

        Number of milliseconds to delay when displaying a visual bell. Default is 100. If set to zero, no visual bell is displayed. This is useful for very slow displays, e.g., an LCD display on a laptop.

vt100Graphics (\fPclass\fB VT100Graphics)

        This specifies whether xterm will interpret VT100 graphic character escape sequences while in UTF-8 mode. The default is \*(``true\*('', to provide support for various legacy applications.

wideBoldFont (\fPclass\fB WideBoldFont)

        This option specifies the font to be used for displaying bold wide text. By default, it will attempt to use a font twice as wide as the font that will be used to draw bold text. If no double-width font is found, it will improvise, by stretching the bold font.

wideChars (\fPclass\fB WideChars)

        Specifies if xterm should respond to control sequences that process 16-bit characters. The default is \*(``false.\*(''

wideFont (\fPclass\fB WideFont)

        This option specifies the font to be used for displaying wide text. By default, it will attempt to use a font twice as wide as the font that will be used to draw normal text. If no double-width font is found, it will improvise, by stretching the normal font.

ximFont (\fPclass\fB XimFont)

        This option specifies the font to be used for displaying the preedit string in the "OverTheSpot" input method.

In "OverTheSpot" preedit type, the preedit (preconversion) string is displayed at the position of the cursor. It is the XIM server's responsibility to display the preedit string. The XIM client must inform the XIM server of the cursor position. For best results, the preedit string must be displayed with a proper font. Therefore, xterm informs the XIM server of the proper font. The font is be supplied by a "fontset", whose default value is "*". This matches every font, the X library automatically chooses fonts with proper charsets. The ximFont resource is provided to override this default font setting.

The following resources are specified as part of the tek4014 widget (class Tek4014). These are specified by patterns such as "XTerm.tek4014.NAME":

font2 (\fPclass\fB Font)

        Specifies the large font to use in the Tektronix window.

fontSmall (\fPclass\fB Font)

        Specifies the small font to use in the Tektronix window.

ginTerminator (\fPclass\fB GinTerminator)

        Specifies what character(s) should follow a GIN report or status report. The possibilities are \*(``none,\*('' which sends no terminating characters, \*(``CRonly,\*('' which sends CR, and \*(``CR&EOT,\*('' which sends both CR and EOT. The default is \*(``none.\*(''

height (\fPclass\fB Height)

        Specifies the height of the Tektronix window in pixels.

initialFont (\fPclass\fB InitialFont)

        Specifies which of the four Tektronix fonts to use initially. Values are the same as for the set-tek-text action. The default is \*(``large.\*(''

width (\fPclass\fB Width)

        Specifies the width of the Tektronix window in pixels.

The following resources are useful when specified for the Athena Scrollbar widget:

thickness (\fPclass\fB Thickness)

        Specifies the width in pixels of the scrollbar.

background (\fPclass\fB Background)

        Specifies the color to use for the background of the scrollbar.

foreground (\fPclass\fB Foreground)

        Specifies the color to use for the foreground of the scrollbar. The \*(``thumb\*('' of the scrollbar is a simple checkerboard pattern alternating pixels for foreground and background color. . .

The selection functions are invoked when the pointer buttons are used with no modifiers, and when they are used with the \*(``shift\*('' key. The assignment of the functions described below to keys and buttons may be changed through the resource database; see ACTIONS below. .

Pointer button one (usually left) is used to save text into the cut buffer. Move the cursor to beginning of the text, and then hold the button down while moving the cursor to the end of the region and releasing the button. The selected text is highlighted and is saved in the global cut buffer and made the PRIMARY selection when the button is released. Normally (but see the discussion of on2Clicks, etc):

• -
     Double-clicking selects by words.
• -
      Triple-clicking selects by lines.
• -
      Quadruple-clicking goes back to characters, etc.

Multiple-click is determined by the time from button up to button down, so you can change the selection unit in the middle of a selection. Logical words and lines selected by double- or triple-clicking may wrap across more than one screen line if lines were wrapped by xterm itself rather than by the application running in the window. If the key/button bindings specify that an X selection is to be made, xterm will leave the selected text highlighted for as long as it is the selection owner. .

Pointer button two (usually middle) \*(``types\*('' (pastes) the text from the PRIMARY selection, if any, otherwise from the cut buffer, inserting it as keyboard input. .

Pointer button three (usually right) extends the current selection. (Without loss of generality, you can swap \*(``right\*('' and \*(``left\*('' everywhere in the rest of this paragraph.) If pressed while closer to the right edge of the selection than the left, it extends/contracts the right edge of the selection. If you contract the selection past the left edge of the selection, xtermassumes you really meant the left edge, restores the original selection, then extends/contracts the left edge of the selection. Extension starts in the selection unit mode that the last selection or extension was performed in; you can multiple-click to cycle through them. .

By cutting and pasting pieces of text without trailing new lines, you can take text from several places in different windows and form a command to the shell, for example, or take output from a program and insert it into your favorite editor. Since cut buffers are globally shared among different applications, you may regard each as a \*(``file\*('' whose contents you know. The terminal emulator and other text programs should be treating it as if it were a text file, i.e., the text is delimited by new lines. .

The scroll region displays the position and amount of text currently showing in the window (highlighted) relative to the amount of text actually saved. As more text is saved (up to the maximum), the size of the highlighted area decreases. .

Clicking button one with the pointer in the scroll region moves the adjacent line to the top of the display window. .

Clicking button three moves the top line of the display window down to the pointer position. .

Clicking button two moves the display to a position in the saved text that corresponds to the pointer's position in the scrollbar. .

Unlike the VT102 window, the Tektronix window does not allow the copying of text. It does allow Tektronix GIN mode, and in this mode the cursor will change from an arrow to a cross. Pressing any key will send that key and the current coordinate of the cross cursor. Pressing button one, two, or three will return the letters \*(``l\*('', \*(``m\*('', and \*(``r\*('', respectively. If the \*(``shift\*('' key is pressed when a pointer button is pressed, the corresponding upper case letter is sent. To distinguish a pointer button from a key, the high bit of the character is set (but this is bit is normally stripped unless the terminal mode is RAW; see tty (4) for details). . .

When configured to use the primary selection, (the default) xterm can provide the selection data in ways which help to retain character encoding information as it is pasted.

A user "selects" text on xterm, which highlights the selected text. A subsequent "paste" to another client forwards a request to the client owning the selection. If xterm owns the primary selection, it makes the data available in the form of one or more "selection targets". If it does not own the primary selection, e.g., if it has released it or another client has asserted ownership, it relies on cut-buffers to pass the data. But cut-buffers handle only ISO-8859-1 data (officially - some clients ignore the rules). .

When configured to use the clipboard (see resource selectToClipboard), the problem with persistence of ownership is bypassed. Otherwise, there is no difference regarding the data which can be passed via selection. .

The different types of data which are passed depend on what the receiving client asks for. These are termed selection targets.

When asking for the selection data, xterm tries the following types in this order:

• UTF8_STRING
       This is an XFree86 extension, which denotes that the data is encoded in UTF-8. When xterm is built with wide-character support, it both accepts and provides this type.
• TEXT
       the text is in the encoding which corresponds to your current locale.
• COMPOUND_TEXT this is a format for multiple character set data, such as multi-lingual text. It can store UTF-8 data as a special case.
• STRING
       This is Latin 1 (ISO-8859-1) data.

The middle two (TEXT and COMPOUND_TEXT) are added if xterm is configured with the i18nSelections resource set to \*(``true\*(''.

UTF8_STRING is preferred (therefore first in the list) since xterm stores text as Unicode data when running in wide-character mode, and no translation is needed. On the other hand, TEXT and COMPOUND_TEXT may require translation. If the translation is incomplete, they will insert X's \*(``defaultString\*('' whose value cannot be set, and may simply be empty. Xterm's defaultString resource specifies the string to use for incomplete translations of the UTF8_STRING.

You can alter the types which xterm tries using the eightBitSelectTypes or utf8SelectTypes resources. For instance, you might have some specific locale setting which does not use UTF-8 encoding. The resource value is a comma-separated list of the selection targets, which consist of the names shown. You can use the special name I18N to denote the optional inclusion of TEXT and COMPOUND_TEXT. The names are matched ignoring case, and can be abbreviated. The default list can be expressed in several ways, e.g.,

UTF8_STRING,I18N,STRING
utf8,i18n,string
u,i,s

.

The xterm mainMenu pops up when the \*(``control\*('' key and pointer button one are pressed in a window. This menu contains items that apply to both the VT102 and Tektronix windows. There are several sections:

• Commands for managing X events:
      .RS
• Toolbar
      Clicking on the "Toolbar" menu entry hides the toolbar if it is visible, and shows it if it is not.
• Secure Keyboard (securekbd)
      The

Secure Keyboard mode is helpful when typing in passwords or other sensitive data in an unsecure environment; see SECURITY below (but read the limitations carefully).

• Allow SendEvents (allowsends)
      Specifies whether or not synthetic key and button events generated using the X protocol SendEvent request should be interpreted or discarded. This corresponds to the allowSendEvents resource.
• Redraw Window (redraw)
      Forces the X display to repaint; useful in some environments.
• Commands for capturing output:
      .RS
• Log to File (logging)
      Captures text sent to the screen in a logfile, as in the -l logging option.
• Print Window (print)
      Sends the text of the current window to the program given in the printerCommand resource.
• Redirect to Printer (print-redir)
      This sets the printerControlMode to 0 or 2. You can use this to turn the printer on as if an application had sent the appropriate control sequence. It is also useful for switching the printer off if an application turns it on without resetting the print control mode.
• Modes for setting keyboard style:
      .RS
• 8-Bit Controls (8-bit-control)
      Enabled for VT220 emulation, this controls whether xterm will send 8-bit control sequences rather than using 7-bit (ASCII) controls, e.g., sending a byte in the range 128-159 rather than the escape character followed by a second byte. Xterm always interprets both 8-bit and 7-bit control sequences (see the document Xterm Control Sequences). This corresponds to the eightBitControl resource.
• Backarrow Key (BS/DEL) (backarrow key)
      Modifies the behavior of the backarrow key, making it transmit either a backspace (8) or delete (127) character. This corresponds to the backarrowKey resource.
• Alt/NumLock Modifiers (num-lock)
      Controls the treatment of Alt- and NumLock-key modifiers. This corresponds to the numLock resource.
• Meta Sends Escape (meta-esc)
      Controls whether Meta keys are converted into a two-character sequence with the character itself preceded by ESC. This corresponds to the metaSendsEscape resource.
• Delete is DEL (delete-is-del)
      Controls whether the Delete key on the editing keypad should send DEL (127) or the VT220-style Remove escape sequence. This corresponds to the deleteIsDEL resource.
• Old Function-Keys (oldFunctionKeys)
• HP Function-Keys (hpFunctionKeys)
• SCO Function-Keys (scoFunctionKeys)
• Sun Function-Keys (sunFunctionKeys)
• VT220 Keyboard (sunKeyboard)
      These act as a radio-button, selecting one style for the keyboard layout. It corresponds to more than one resource setting:

R

R

R

R

• Commands for process signalling:
      .RS
• Send STOP Signal (suspend)
• Send CONT Signal (continue)
• Send INT Signal (interrupt)
• Send HUP Signal (hangup)
• Send TERM Signal (terminate)
• Send KILL Signal (kill)
      These send the SIGTSTP, SIGCONT, SIGINT, SIGHUP, SIGTERM and SIGKILL signals respectively, to the process group of the process running under xterm(usually the shell). The

SIGCONT function is especially useful if the user has accidentally typed CTRL-Z, suspending the process.

• Quit (quit)
      Stop processing X events except to support the -hold option, and then send a SIGHUP signal to the the process group of the process running under xterm(usually the shell).

.

The vtMenusets various modes in the VT102 emulation, and is popped up when the \*(``control\*('' key and pointer button two are pressed in the VT102 window.

      Reset scroll regions. This can be convenient when some program has left the scroll regions set incorrectly (often a problem when using VMS or TOPS-20). This corresponds to the VT220 DECSTR control sequence. .
• Do Full Reset (hardreset)
      The full reset entry will clear the screen, reset tabs to every eight columns, and reset the terminal modes (such as wrap and smooth scroll) to their initial states just after xtermhas finished processing the command line options. This corresponds to the VT102 RIS control sequence, with a few obvious differences. For example, your session is not disconnected as a real VT102 would do. .
• Reset and Clear Saved Lines (clearsavedlines)
      Perform a full reset, and also clear the saved lines. .
• Commands for setting the current screen:
      .RS .
• Show Tek Window (tekshow)
      When enabled, pops the Tektronix 4014 window up (makes it visible). When disabled, hides the Tektronix 4014 window. .
• Switch to Tek Mode (tekmode)
      When enabled, pops the Tektronix 4014 window up if it is not already visible, and switches the input stream to that window. When disabled, hides the Tektronix 4014 window and switches input back to the VTxxx window. .
• Hide VT Window (vthide)
      When enabled, hides the VTxxx window, shows the Tektronix 4014 window if it was not already visible and switches the input stream to that window. When disabled, shows the VTxxx window, and switches the input stream to that window. .
• Show Alternate Screen (altscreen)
      When enabled, shows the alternate screen. When disabled, shows the normal screen. Note that the normal screen may have saved lines; the alternate screen does not.

The fontMenu pops up when when the \*(``control\*('' key and pointer button three are pressed in a window. It sets the font used in the VT102 window, or modifies the way the font is specified or displayed. There are several sections.

The first section allows you to select the font from a set of alternatives:

• Default (fontdefault)
      Set the font to the default, i.e., that given by the

*VT100.font resource.

• Unreadable (font1)
      Set the font to that given by the

*VT100.font1 resource.

• Tiny (font2)
      Set the font to that given by the

*VT100.font2 resource.

• Small (font3)
      Set the font to that given by the

*VT100.font3 resource.

• Medium (font4)
      Set the font to that given by the

*VT100.font4 resource.

• Large (font5)
      Set the font to that given by the

*VT100.font5 resource.

• Huge (font6)
      Set the font to that given by the

*VT100.font6 resource.

• Escape Sequence
      This allows you to set the font last specified by the Set Font escape sequence (see the document Xterm Control Sequences).
• Selection (fontsel)
      This allows you to set the font specified the current selection as a font name (if the PRIMARY selection is owned).

The second section allows you to modify the way it is displayed:

• Line-Drawing Characters (font-linedrawing)
      When set, tells xterm to draw its own line-drawing characters. Otherwise it relies on the font containing these. Compare to the forceBoxChars resource.
• Packed Font (font-packed)
      When set, tells xterm to use the minimum glyph-width from a font when displaying characters. Use the maximum width (unchecked) to help display proportional fonts. Compare to the forcePackedFont resource.
• Doublesized Characters (font-doublesize)
      When set, xterm may ask the font server to produce scaled versions of the normal font, for VT102 double-size characters.

The third section allows you to modify the way it is specified:

• TrueType Fonts (render-font)
      If the

renderFont and corresponding resources were set, this is a further control whether xterm will actually use the Xft library calls to obtain a font.

• UTF-8 (utf8-mode)
      This controls whether xterm uses UTF-8 encoding of input/output. It is useful for temporarily switching xterm to display text from an application which does not follow the locale settings.

The fourth section allows you to enable or disable special operations which can be controlled by writing escape sequences to the terminal. These are disabled if the SendEvents feature is enabled:

• Allow Color Ops (allow-font-ops)
      This corresponds to the allowColorOps resource. Enable or disable control sequences that set/query the colors.
• Allow Font Ops (allow-font-ops)
      This corresponds to the allowFontOps resource. Enable or disable control sequences that set/query the font.
• Allow Tcap Ops (allow-tcap-ops)
      Enable or disable control sequences that query the terminal's notion of its function-key strings, as termcap or terminfo capabilities. This corresponds to the allowTcapOps resource.
• Allow Title Ops (allow-title-ops)
      Enable or disable control sequences that modify the window title or icon name. This corresponds to the allowTitleOps resource.
• Allow Window Ops (allow-window-ops)
      Enable or disable extended window control sequences (as used in dtterm). This corresponds to the allowWindowOps resource. .

The tekMenusets various modes in the Tektronix emulation, and is popped up when the \*(``control\*('' key and pointer button two are pressed in the Tektronix window. The current font size is checked in the modes section of the menu.

• Large Characters (tektextlarge)
• #2 Size Characters (tektext2)
• #3 Size Characters (tektext3)
• Small Characters (tektextsmall)

Commands:

• PAGE (tekpage)
      Clear the Tektronix window.
• RESET (tekreset)
• COPY (tekcopy)

Windows:

• Show VT Window (vtshow)
• Switch to VT Mode (vtmode)
• Hide Tek Window (tekhide) . .
