PROGRAM:
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
-t, --text-setup
When starting orca, initiate the text-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.
