<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 two tabs: <link linkend="access-bell"
><guilabel
>Bell</guilabel
></link
> and <link linkend="access-kb"
><guilabel
>Keyboard</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 labelled <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 labelled <guilabel
>Use customised bell</guilabel
>, and enter the complete pathname to the sound file in the text box labelled <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 colour across it) when the system bell would normally sound. </para>
<para
>To use the visible bell, first place a mark in the check box labelled <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 colours on the screen will be reversed. If you choose <guilabel
>Flash screen</guilabel
>, you can choose the colour 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>

<listitem>
<para
>If this option is enabled, the user 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 labelled <guilabel
>Lock Sticky Keys</guilabel
>. If this check box is enabled, the &Alt;, &Ctrl; and &Shift; keys stay <quote

>de-selected</quote
> by the user. </para>

<variablelist>
<varlistentry>
<term
>With <guilabel
>Lock Sticky Keys</guilabel
> disabled:</term>
<listitem>
<para
>The user presses the &Shift; key, then presses the <keycap
>F</keycap
> key. The computer translates this into <keycombo action="simul"
>&Shift;<keycap
>F</keycap
></keycombo
>. Now if the user types a <keycap
>p</keycap
>, the computer interprets this as the letter p (no shift). </para>

>With <guilabel
>Lock Sticky Keys</guilabel
