<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 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>
</sect3>
<sect3 id="access-kb">
<title><guilabel>Keyboard</guilabel></title>
<para>There are three sections to this panel.</para>
<variablelist>
<varlistentry>
<term><guilabel>Use Sticky Keys</guilabel></term>
<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>selected</quote> until they are <quote>de-selected</quote> by the user. </para>
<para>As an example: </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>
</listitem>
</varlistentry>
<varlistentry>
<term>With <guilabel>Lock Sticky Keys</guilabel> enabled:</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 (<keycombo action="simul">&Shift;<keycap>P</keycap></keycombo>). </para>
</listitem>
</varlistentry>
</variablelist>
</listitem>
</varlistentry>
<varlistentry>
<term><guilabel>Slow keys</guilabel></term>
<listitem>
<para>If this option is enabled, the user must hold the key down for a specified period of time (adjustable with the slider) before the keystroke will be accepted. This helps prevent accidental key strokes. </para>
</listitem>
</varlistentry>
<varlistentry>
<term><guilabel>Bounce keys</guilabel></term>
<listitem>
<para>If this option is enabled, the user must wait a specified delay (configurable with the slider) before the next key press can be accepted. This prevents accidental multiple key strokes. </para>
