  32 <para>This module is designed to help users who have difficulty hearing
  33 audible cues, or who have difficulty using a keyboard.  </para>
  34
  35 <para>
  36 The module is divided into two tabs: <link
  37 linkend="access-bell"><guilabel>Bell</guilabel></link> and <link
  38 linkend="access-kb"><guilabel>Keyboard</guilabel></link>.

  43
  44 <para>
  45 This panel is divided into an <guilabel>Audible Bell</guilabel> section
  46 and a <guilabel>Visible Bell</guilabel> section.
  47 </para>
  48
  49 <para>
  50 The top check box labeled <guilabel>Use System Bell</guilabel>, determines
  51 whether the normal System bell rings.  If this option is disabled, the
  52 System bell will be silenced.
  53 </para>
  54
  55 <para>
  56 The next check box down can be used to play a different sound whenever
  57 the system bell is triggered.  To activate, place a mark in the check
  58 box labeled <guilabel>Use customized bell</guilabel>, and enter the
  59 complete pathname to the sound file in the text box labeled
  60 <guilabel>Sound to Play</guilabel>.  If you want, you can select the
  61 <guibutton>Browse</guibutton> button to navigate through your filesystem
  62 to find the exact file.
  63 </para>
  64
  65 <para>
  66 For those users who have difficulty hearing the System bell, or those
  67 users who have a silent computer, &kde; offers the <emphasis>visible bell</emphasis>.  This
  68 provides a visual signal (inverting the screen or flashing a color
  69 across it) when the system bell would normally sound.
  70 </para>
  71
  72 <para>
  73 To use the visible bell, first place a mark in the check box labeled
  74 <guilabel>Use visible bell</guilabel>.
  75 </para>
  76
  77 <para>
  78 You can then select between <guilabel>Invert screen</guilabel>, or
  79 <guilabel>Flash screen</guilabel>.  If you select <guilabel>Invert
  80 screen</guilabel>, all colors on the screen will be reversed.  If you
  81 choose <guilabel>Flash screen</guilabel>, you can choose the color by
  82 clicking the button to the right of the <guilabel>Flash
  83 screen</guilabel> selection.
  84 </para>
  85
  86 <para>
  87 The slider bar can be used to adjust the duration of the visible
  88 bell.  The default value is 500ms, or half a second.

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

 101 <listitem>
 102 <para>
 103 If this option is enabled, you can press and release the &Shift;,
 104 &Alt; or &Ctrl; keys, and then press another key to get a key combo
 105 (example: <keycombo action="simul">&Ctrl; &Alt;
 106 <keycap>Del</keycap></keycombo> could be done with &Ctrl; then &Alt;
 107 then <keycap>Del</keycap>).
 108 </para>
 109
 110 <para>
 111 Also in this section is a check box labeled <guilabel>Lock Sticky
 112 Keys</guilabel>.  If this check box is enabled, the &Alt;, &Ctrl;
 113 and &Shift; keys stay <quote>selected</quote> until you
 114 <quote>de-selected</quote> them.
 115 </para>
 116
 117 <para>
 118 As an example:
 119 </para>
 120 <variablelist>
 121 <varlistentry>
 122 <term>With <guilabel>Lock Sticky Keys</guilabel> disabled:</term>
 123 <listitem>
 124 <para>If you press the &Shift; key then press the
 125 <keycap>F</keycap> key, the computer interprets this as <keycombo
 126 action="simul">&Shift;<keycap>F</keycap></keycombo>.  Now if you
 127 type a <keycap>P</keycap>, the computer interprets this as the letter p
 128 (no shift).
 129 </para>
 130 </listitem>
 131 </varlistentry>
 132
 133 <varlistentry>
 134 <term>With <guilabel>Lock Sticky Keys</guilabel> enabled:</term>
 135 <listitem>
 136 <para>
 137 If you press the &Shift; key <emphasis>twice</emphasis> then press the <keycap>F</keycap> key,
 138 the computer interprets this as <keycombo
 139 action="simul">&Shift;<keycap>F</keycap></keycombo>.  Now if you
 140 type a <keycap>p</keycap>, the computer interprets this as the letter P
 141 (<keycombo action="simul">&Shift;<keycap>P</keycap></keycombo>). To
 142 de-select the &Shift; key, press it again.

 150 <varlistentry>
 151 <term><guilabel>Slow keys</guilabel></term>
 152 <listitem>
 153 <para>
 154 If this option is enabled, you must hold the key down for a
 155 specified length of time (adjustable with the slider) before the
 156 keystroke will be accepted. This helps prevent accidental key strokes.
 157 </para>

 161 <varlistentry>
 162 <term><guilabel>Bounce keys</guilabel></term>

 164 <para>
 165 If this option is enabled, you must wait for a specified length of time
 166 (configurable with the slider) before the next key press can be
 167 accepted. This prevents accidental multiple key strokes.
