<para>This module is designed to help users who have difficulty hearing
|
|
audible cues, or who have difficulty using a keyboard.</para>
|

<para>
|

The module is divided into four tabs tabs:
|
|
<link linkend="access-bell"><guilabel>Bell</guilabel></link>,
|
|
<link linkend="modifier-keys"><guilabel>Modifier Keys</guilabel></link>,
|

<link linkend="keyboard-filters"><guilabel>Keyboard Filters</guilabel></link>
|
|
and <link linkend="action-gestures"><guilabel>Action Gestures</guilabel></link>.

<sect3 id="access-bell">

<title><guilabel>Bell</guilabel></title>
|
|
|
|
<para>
|
|
This panel is divided into an <guilabel>Audible Bell</guilabel> section
|
|
and a <guilabel>Visible Bell</guilabel> section.
|
|
</para>
|
|
|
|
<para>
|
|
The top check box labeled <guilabel>Use System Bell</guilabel>, determines
|
|
whether the normal System bell rings. If this option is disabled, the
|
|
System bell will be silenced.
|
|
</para>
|
|
|
|
<para>
|
|
The next check box down can be used to play a different sound whenever
|
|
the system bell is triggered. To activate, place a mark in the check
|
|
box labeled <guilabel>Use customized bell</guilabel>, and enter the
|
|
complete pathname to the sound file in the text box labeled
|
|
<guilabel>Sound to Play</guilabel>. If you want, you can select the
|
|
<guibutton>Browse</guibutton> button to navigate through your filesystem
|
|
to find the exact file.

|
|
|
<para>
|
|
For those users who have difficulty hearing the System bell, or those
|
|
users who have a silent computer, &tde; offers the <emphasis>visible bell</emphasis>. This
|
|
provides a visual signal (inverting the screen or flashing a color
|
|
across it) when the system bell would normally sound.
|
|
</para>
|
|
|
|
<para>
|
|
To use the visible bell, first place a mark in the check box labeled
|
|
<guilabel>Use visible bell</guilabel>.
|
|
</para>
|
|
|
|
<para>
|
|
You can then select between <guilabel>Invert screen</guilabel>, or
|
|
<guilabel>Flash screen</guilabel>. If you select <guilabel>Invert
|
|
screen</guilabel>, all colors on the screen will be reversed. If you
|
|
choose <guilabel>Flash screen</guilabel>, you can choose the color by
|
|
clicking the button to the right of the <guilabel>Flash
|
|
screen</guilabel> selection.
|
|
</para>
|
|
