+<title>For Users with Disabilities</title>
+<para>This section of the documentation discusses accessibility features in &kspread;
+for users with disabilities. Some of these features apply to &kde; as a whole and are controlled from
+<ulink url="help:kcontrol">&kcontrolcenter;</ulink>. Some apply to all &koffice; applications,
+and some are specific to &kspread;.</para>

+<para>
+Most of the features described in this chapter are enabled by installing the
+<command>kdeaccessibility</command> module.
+The <command>kdeaccessibility</command> module is part of the &kde; project
+<ulink url="http://www.kde.org">http://www.kde.org</ulink>. The <command>kdeaccessibility</command>
+package can be obtained from &kde-ftp;, the
+main ftp site of the &kde; project.

+
+<para>Many distributions offer precompiled binaries on their ftp sites. Please check your distribution's web sites for more information.</para>

+KTTS. See <ulink url="help:kttsd">The KTTS Handbook</ulink> for details.
+To turn on the TTS feature in &kspread;,
+select <menuchoice><guimenu>Settings</guimenu><guimenuitem>Configure

+This will display a dialog box.

+Check the <guilabel>Move pointer with keyboard (using the num pad)</guilabel> box. When you do this, the other settings will become enabled, and you can customize the keyboard pointer behavior further, if required.
+ The various keys on the number pad move in the direction you would expect. Note that you can move diagonally as well as up, down, left and right. The <keycap>5</keycap> key emulates a click to a pointer button, typically &LMB;. You change which button is emulated by using the <keycap>/</keycap> key (which makes it &LMB;),
+<keycap>*</keycap> key (which makes it middle mouse button) and <keycap>-</keycap> (which makes it &RMB;).
+ Using the <keycap>+</keycap> emulates a doubleclick to the selected pointer button. You can use the
+<keycap>0</keycap> key to emulate holding down the selected pointer button (for easy dragging),
+and then use the <keycap>.</keycap> to emulate releasing the selected pointer button.
