orca: a scriptable screen reader

NAME

orca - a scriptable screen reader

SYNOPSIS

orca [option...]

DESCRIPTION

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

orca works with applications and toolkits that support the Assistive Technology Service Provider Interface (AT-SPI), which is the primary assistive technology infrastructure for Linux and Solaris. Applications and toolkits supporting the AT-SPI include the GNOME Gtk+ toolkit, the Java platform's Swing toolkit, LibreOffice, Gecko, and WebKitGtk. AT-SPI support for the KDE Qt toolkit is being pursued.

OPTIONS

-s, --setup

When starting orca, initiate the GUI-based configuration.

-u, --user-prefs-dir=dirname

When starting orca, use dirname as an alternate directory for the user preferences.

-e, --enable=speech|braille|braille-monitor

When starting orca, force the enabling of the supplied options.

-d, --disable=speech|braille|braille-monitor

When starting 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.

--debug-file=filename

Enables debug output for 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 orca process. By default, if orca detects an existing orca process for the same session, it will not start a new orca process. This option will kill and cleanup after any existing orca process and then start a new orca in its place.

KEYBOARD SETTINGS

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.

Orca uses default GNOME keyboard shortcuts to navigate the desktop and interact with various applications. The flat review commands provide an alternative method of interaction in certain inaccessible applications. It should not be confused with flat review functionality provided by other screen readers.
