<title>Introduction</title>
<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: <link
linkend="access-bell"><guilabel>Bell</guilabel></link>, <link
linkend="access-modifier-keys"><guilabel>Modifier keys</guilabel></link>, <link
linkend="access-keyboard-filters"><guilabel>Keyboard Filters</guilabel></link> and <link
linkend="access-activation-gestures"><guilabel>Activation Gestures</guilabel></link>.
</para>
<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>
<para>
For those users who have difficulty hearing the System bell, or those
users who have a silent computer, &kde; 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>
<para>
The slider bar can be used to adjust the duration of the visible
bell. The default value is 500ms, or half a second.
</para>
</sect3>
<sect3 id="access-modifier-keys">
<title><guilabel>Modifier keys</guilabel></title>
<para>There are the two sections <guilabel>Sticky Keys</guilabel>
and <guilabel>Locking Keys</guilabel> to this panel.</para>
<variablelist>
<varlistentry>
<term><guilabel>Use Sticky Keys</guilabel></term>
<listitem>
<para>
If this option is enabled, you can press and release the &Shift;,
&Alt; or &Ctrl; keys, and then press another key to get a key combo
(example: <keycombo action="simul">&Ctrl; &Alt;
<keycap>Del</keycap></keycombo> could be done with &Ctrl; then &Alt;
then <keycap>Del</keycap>).
</para>
<para>
Also in this section is a check box labeled <guilabel>Lock Sticky
Keys</guilabel>. If this check box is enabled, the &Alt;, &Ctrl;
and &Shift; keys stay <quote>selected</quote> until you
<quote>de-selected</quote> them.
</para>
<para>
As an example:
</para>
<variablelist>
<varlistentry>
<term>With <guilabel>Lock Sticky Keys</guilabel> disabled:</term>
<listitem>
<para>If you press the &Shift; key then press the
<keycap>F</keycap> key, the computer interprets this as <keycombo
action="simul">&Shift;<keycap>F</keycap></keycombo>. Now if you
type a <keycap>P</keycap>, the computer interprets this as the letter p
(no shift).
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>With <guilabel>Lock Sticky Keys</guilabel> enabled:</term>
<listitem>
<para>
If you press the &Shift; key <emphasis>twice</emphasis> then press the <keycap>F</keycap> key,
the computer interprets this as <keycombo
action="simul">&Shift;<keycap>F</keycap></keycombo>. Now if you
type a <keycap>P</keycap>, the computer interprets this as the letter P
(<keycombo action="simul">&Shift;<keycap>P</keycap></keycombo>). To
de-select the &Shift; key, press it again.
