 Braille Preferences
Enable Braille Support

This check box toggles whether or not Orca will make use of a braille display. If BrlTTY is not running, Orca will recover gracefully and will not communicate with the braille display.

Default value: not checked

If you configure BrlTTY later on, you need to restart Orca in order to use braille.

Enable Braille Monitor

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.

Default value: not checked

Enable Contracted Braille

Orca supports contracted braille via the liblouis project. Because many distros include liblouis, you will likely automatically have access to contracted braille support in Orca.

To enable contracted braille on a system where liblouis has been installed, be sure that the Enable Contraced Braille checkbox is checked. Then choose your desired translation table from the Contraction Table combo box.

Default value: not checked

Abbreviated Role Names

This check box determines the manner in which role names are displayed and can be used to help conserve real estate on the braille display. For instance, if a slider had focus, the word "slider" would be displayed if abbreviated role names is not checked; if it were checked, "sldr" would be displayed instead.

Default value: not checked

Disable end of line symbol

Checking this checkbox tells Orca to not present the "$l" string at the end of a line of text.

Default value: not checked

Verbosity

This radio button group determines the amount of information that will be brailled in certain situations. For example, if it is set to verbose, keyboard shortcut and role name information is displayed. This information is not displayed in brief mode.

Default value: Verbose
