NAME

       orca - is 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.

       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.

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|main-window
	      When starting orca, force the enabling of the supplied options.

       -d, --disable=speech|braille|braille-monitor|main-window
	      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  func-
	      tionality provided by other screen readers.
