<title>Enable Braille Support</title>
<p>
This check box toggles whether or not <app>Orca</app> will make
use of a braille display. If BrlTTY is not running, <app>Orca</app>
will recover gracefully and will not communicate with the braille
display.
</p>
<p>
Default value: not checked
</p>
<note style="tip">
<p>
If you configure BrlTTY later on, you need to restart <app>Orca</app>
in order to use braille.
</p>
</note>
</section>
<section id="braillewordwrap">
<title>Enable word wrap</title>
<p>
If <gui>Enable word wrap</gui> is checked, <app>Orca</app> will adjust the
text so that only full words are shown on the braille display. If it is not
checked, <app>Orca</app> will use all of the cells on the display so that
more text can be shown at once.
</p>
<p>
Default value: not checked
</p>
</section>
<section id="contractedbraille">
<title>Enable Contracted Braille</title>
<p>
Orca supports contracted braille via the liblouis project. Because many
distros include liblouis, you will likely automatically have access to
contracted braille support in <app>Orca</app>.
</p>
<p>
To enable contracted braille on a system where liblouis has been installed,
be sure that the <gui>Enable Contracted Braille</gui> checkbox is checked.
Then choose your desired translation table from the <gui>Contraction
Table</gui> combo box.
</p>
<p>
Default value: not checked
</p>
</section>
<section id="rolenames">
<title>Abbreviated Role Names</title>
<p>
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.
</p>
<p>
Default value: not checked
</p>
</section>
<section id="eolindicator">
<title>Disable end of line symbol</title>
<p>
Checking this checkbox tells <app>Orca</app> to not present the
"$l" string at the end of a line of text.
</p>
<p>
Default value: not checked
</p>
</section>
<section id="verbosity">
<title>Verbosity</title>
<p>
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.
</p>
<p>
Default value: <gui>Verbose</gui>
</p>
</section>
<section id="selectionandhyperlink">
<title>Selection and Hyperlink Indicators</title>
<p>
The <gui>Selection Indicator</gui> and <gui>Hyperlink Indicator</gui>
radio button groups allow you to configure <app>Orca</app>'s behavior
when displaying selected text and hyperlinks. By default, when you
encounter either, <app>Orca</app> will "underline" that text on
your braille display with Dots 7 and 8. If you would prefer, you
can change the indicator to only be Dot 7, only be Dot 8, or not
be present at all.
</p>
<p>
Default value: <gui>Dots 7 and 8</gui>
</p>
<note style="tip">
<title>Text Attribute Indicators</title>
<p>
You can also optionally have text attributes indicated in braille.
Enabling this feature and choosing which attributes are of
interest is done on the <link xref="preferences_text_attributes">
<gui>Text Attributes</gui> page</link> of the preferences dialog.
</p>
</note>

<section id="flashMessageSettings">
<title>Flash Message Settings</title>
<p>
Flash messages are similar in nature to notifications or announcements:
They are shown on your refreshable braille display for a brief time,
after which the original contents of the braille display are restored.
<app>Orca</app> has several settings you can use to control flash message
presentation.
</p>
<section id="flashMessageSettings_enable">
<title>Enable flash messages</title>
<p>
If <gui>Enable flash messages</gui> is checked, <app>Orca</app> will
present messages to you in braille. If you prefer to only have
<app>Orca</app>'s messages spoken, you should uncheck this checkbox.
</p>
<p>
Default value: checked
</p>
</section>
<section id="flashMessageSettings_detailed">
<title>Messages are detailed</title>
<p>
If <gui>Messages are detailed</gui> is checked, <app>Orca</app> will
present detailed messages to you in braille. For instance, if you
use <app>Orca</app>'s command to change echo, <app>Orca</app> might
display "Echo set to word." If you would prefer shorter messages,
such as simply "word," you should uncheck this checkbox.
</p>
<p>
Default value: checked
</p>
</section>
<section id="flashMessageSettings_persistent">
<title>Messages are persistent</title>
<p>
As stated above, flash messages are only shown for a brief period of time.
If you would prefer messages remain displayed until you perform an action
which causes your display to be updated, you should check the <gui>Messages
are persistent</gui> checkbox.
</p>
<p>
Default value: not checked
</p>
</section>
<section id="flashMessageSettings_duration">
<title>Duration (secs)</title>
<p>
The amount of time <app>Orca</app> will wait before removing the message and
restoring the original contents of your display can be set in the <gui>
Duration (secs)</gui> spin button. Note that the value of this
setting will be ignored if you have enabled persistent flash messages.
</p>
<p>
Default value: 5
