<title>Introduction</title>

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

<para>The module is divided into three tabs: <link
linkend="access-bell"><guilabel>Bell</guilabel></link>, <link
linkend="access-kb"><guilabel>Keyboard</guilabel></link>, <link
linkend="access-mouse"><guilabel>Mouse</guilabel></link>.</para>

<sect3 id="access-bell">
<title>Bell</title>

<para>This panel is divided into an <guilabel>Audio Bell</guilabel> section and
a <guilabel>Visual Bell</guilabel> Section.</para>

<para>The top check box labelled <guilabel>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 customized bell</guilabel>, and enter the complete pathname to
the sound file in the blank 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 Visual bell.  This "bell" can
be configured to invert the screen, or to flash a color across the
screen.</para>

<para>To use the visual 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 Invert screen, all colors on
the screen will be reversed.  If you choose Flash color, you can choose the
color by pressing the button to the right of the <guilabel>Flash
Screen</guilabel> selction.</para>

<para>The slider bar can be used to adjust the duration of the visual
bell.</para>

<sect3 id="access-kb">
<title><guilabel>Keyboard</guilabel></title>

<para>There are three sections to this panel.</para>

<variablelist>
<varlistentry><term><guilabel>Sticky Keys</guilabel></term>
<listitem><para>If this option is enabled, the user can press and release the
<keycap>Shift</keycap>, <keycap>Alt</keycap> or <keycap>Control</keycap> keys,
and then press another key to get a key combo (example:
<keycombo><keycap>Ctrl</keycap> <keycap>Alt</keycap>
<keycap>Del</keycap></keycombo> could be done with <keycap>Ctrl</keycap> then
<keycap>Alt</keycap> then <keycap>Del</keycap>).</para>
<para>Also in this section is a checkbox labeled <guilabel>Lock Sticky
Keys</guilabel>.  If this checkbox is enabled, then the <keycap>Alt</keycap>,
<keycap>Ctrl</keycap>, and <keycap>Shift</keycap> keys stay
<quote>selected</quote> until they are <quote>de-selected</quote> by the user.</para>
<para>As an example:</para>
<para>With <guilabel>Lock Sticky Keys</guilabel> disabled- The user types the
<keycap>Shift</keycap> key, then press the <keycap>F</keycap> key.  The computer
translates this into
<keycombo><keycap>Shift</keycap><keycap>F</keycap></keycombo>.  Now if the user
types a <keycap>p</keycap>, the computer interprets this as the letter p (no
shift).  </para>
<para>With <guilabel>Lock Sticky Keys</guilabel> enabled - The user types the
<keycap>Shift</keycap> key, then press the <keycap>F</keycap> key.  The computer
translates this into
<keycombo><keycap>Shift</keycap><keycap>F</keycap></keycombo>.  Now if the user
types a <keycap>p</keycap>, the computer interprets this as the letter
<keycombo><keycap>Shift</keycap><keycap>P</keycap></keycombo>.  </para>

</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 keypresses.</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 multiple key strokes from people with tremors.</para></listitem>
</varlistentry>
</variablelist>

<sect3 id="access-mouse">
<title><guilabel>Mouse Navigation</guilabel></title>

the numeric keypad as a replacement.</para>

<para>To enable this option, place a mark in the check box labeled
<guilabel>Move mouse with keyboard</guilabel>.</para>
