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.
