The first time Orca is launched you will be presented with a list of languages from
which to choose. Enter the ID number of your language (for example,
7
for American
English) and press Enter .
When you run Orca for the first time, it will automatically enter setup mode. If you
want to run setup at some later point, you can pass the
setup
option to Orca the next
time you run it. Furthermore, while Orca is running you can press Ins + Space to bring
up Orca's configuration GUI. Finally, Orca provides a text setup utility that you can
start by passing the
--text-setup
option to Orca. All of these options will create
a
~/.orca/user-settings.py
file that holds your Control Center and will also
enable the accessibility infrastructure. You need to log out and log back in for the new
setting to take effect.
Start Orca by typing
orca
in a terminal session window. You can do so from a virtual
console window if you do not yet have access to the GUI. With the GUI installed you
can also press
Alt + F2 to bring up the Run dialog and then type the command
orca
(followed by any optional parameters) and press Enter . Orca will automatically enter
text setup mode if you run it from a virtual console window or if your GUI environment
is not yet set up for accessibility.
To quit Orca press Ins + Q (or CapsLock + Q in laptop layout mode). A Confirmation
dialog will appear.
4.3.2 Braille Page
The braille page allows you to customize various aspects of braille usage.
The first control on the braille page is the Enable braille support check box. This check
box toggles whether or not Orca will make use of a braille display.
Orca's braille monitor provides an on-screen representation of what takes place on the
braille display. This feature is mostly for demonstration purposes, but is also useful for
Orca developers who do not have access to a braille display.
The Abbreviated role names check box determines the manner in which role names are
displayed and can be used to help conserve real estate on the braille display.
When checked, this feature tells Orca to not present the
$1
string at the end of a line.
