orca - is a scriptable screen reader and magnifier

orca [ option... ]

orca is a screen reader for people with visual impairments, it provides alternative access to the desktop by using speech synthesis, braille, and magnification.

In addition,

orca only provides access to applications/toolkits that support the assistive technology service provide interface (AT-SPI), which include GTK, Mozilla, Firefox, Evolution, OpenOffice, StarOffice, Java/Swing, etc.

WARNING: suspending

orca, e.g. by pressing Control-Z, from an AT-SPI enabled shell (such as gnome-terminal), can also suspend the desktop until Orca is killed.

-s, --setup, --gui-setup

    When starting

R orca , bring up the GUI configuration dialog.

-t, --text-setup

    When starting

R orca , initiate the text-based configuration.

-n, --no-setup

    When starting

R orca , force the application to be started without configuration, even though it might have needed it. This is useful when starting

orca via something like gdm.

• -u, --user-prefs-dir= dirname
      When starting

R orca , use dirnameas an alternate directory for the user preferences.

      When starting

R orca , force the disabling of the supplied options.

-l, --list-apps

    Prints the names of all the currently running applications. This is used primarily for debugging purposes to see if

orca can talk to the accessibility infrastructure. Note that if

orca is already running, this will not kill the other

orca process. It will just list the currently running applications, and you will see

orca listed twice: once for the existing

orca and once for this instance.

--debug

    Enables debug output for

orca and sends all debug output to a file with a name of the form 'debug-YYYY-MM-DD-HH:MM:SS.out' in the current directory. The YYYY-MM-DD-HH:MM:SS portion will be replaced with the current date and time.

orca and sends all debug output to the given filename.

-v, --version

    outputs

orca version number and exits.

-?, -h, --help

    displays

orca help and exits.

--replace

    Replace a currently running

R orca process. By default, if

R orca detects an existing

R orca process for the same session, it will not start a new

R orca process. This option will kill and cleanup after any existing

R orca process and then start a new

R orca in its place.

-q, --quit

    Kill and cleanup after any existing Orca process.

Orca provides two keyboard modes, Desktop and Laptop keyboard layout. The

Orca_Modifier key is

Insert in desktop keyboard layout and

Caps_Lock in laptop keyboard layout.
