<para>
Log in to the desktop even if the user cannot easily use the screen, mouse, or keyboard in the usual way.
</para>
</listitem>

<para>
Launch assistive technologies at login time by
associating a user action with an assistive technology application. The user can perform the user action from the standard keyboard, or from a keyboard, pointing device, or switch device that is attached to the USB or
PS/2 mouse port. These user actions are called gestures.
</para>
</listitem>

<para>
Change the visual appearance of the login dialog before the user logs in; for example, using a high-contrast theme for better visibility.

</para>
<para>
and replace the line with the following:
</para>
<para>
<literal>AddGtkModules=true</literal>

Search the file for the following line:
</para>
<para>

and delete the <literal>#</literal> from the start of the line so that the line reads:
</para>
<para>
<literal>

</para>
<note>
<para>
The above lines must be displayed as single lines in the <filename>gdm.conf</filename> file without line breaks. The formatting of this guide may display the lines as being longer than two lines.
</para>

<para>
This step loads all of the GtkModules to enable assistive technologies such as 
<application>On-Screen Keyboard</application>
and <application>Screen Reader and Magnifier
</application>. You can edit the line above further to load only the GtkModules that you require to support the user base. For example: 
</para>

<para>
If you need to use the <application>
Screen Reader and Magnifier</application>, include <literal>gail</literal> and <literal>atk-bridge</literal>.

</listitem>
<listitem>
<para>
If you use pointing devices with switches, alternative physical keyboards, or switch and button devices, include <literal>keymouselistener</literal>.

If you load the <literal>keymouselistener</literal> and 
<literal>dwellmouselistener</literal> GtkModules in the GDM configuration file, you can assign user actions to launch specific assistive technologies at login time. These user actions are called gestures. The gesture associations are contained in the following

If you modify these files, you must restart your system before the changes take effect.
</para>

<para>
The following sections contain examples of the gestures that you can add to the GDM configuration files.
</para>
<note>
<para>
The gestures must be contained in a single line in the <filename>AccessKeyMouseEvents

</para>
</note>

<section id="sysadmin-30">
<title>Starting the Screen Reader Using a Keyboard 
Shortcut</title>
<para>
Edit the <filename>AccessKeyMouseEvents</filename> file to associate keyboard shortcuts with assistive technologies. For example, the following line enables 
you to press and hold <keycombo><keycap>Ctrl</keycap><keycap>S</keycap></keycombo>
for one second to start <application>Screen Reader and Magnifier</application> in speech and Braille mode:
</para>
<para>
<literal>
&lt;Control&gt;s 1 1000 10000 srcore --login

</section>

<section id="sysadmin-41">
<title>Starting Magnifier Using a Keyboard Shortcut
</title>
<para>
Edit the <filename>AccessKeyMouseEvents</filename> file to associate keyboard shortcuts with assistive technologies. For example, the following line enables you to press and hold <keycombo><keycap>Ctrl</keycap>
<keycap>M</keycap></keycombo> for one second to start <application>Screen Reader and 
Magnifier</application> in magnifier mode:
</para>
<para>
<literal>&lt;Control&gt;m 1 1000 10000 srcore --login --enable-magnifier
--disable-speech</literal>
</para>
</section>

<section id="sysadmin-31">
<title>Starting On-Screen Keyboard Using a Switch or Button Gesture</title>
<para>
Edit the <filename>AccessKeyMouseEvents</filename> file to associate switch, key, or button gestures with assistive technologies. Since the primary input device for many <application>On-Screen Keyboard</application> 
users is a switch or button, this is a good way to enable users to start <application>On-Screen Keyboard</application> at login time. 
</para>
<para>
If there is a tendency for a user to start an 
application unintentionally, you can associate the gestures with multiple switch presses or minimum durations. For example, the following line starts <application>On-Screen Keyboard</application> in inverse scanning mode when the user presses the 
switch that is defined as Switch 2 three times within two seconds, for a minimum of 100 milliseconds for each press:
</para>
<para>
<literal>&lt;Switch2&gt;3 100 2000 gok --login --accessmethod=inversescanning
--scan-action=switch1 --select-action=switch2</literal>
</para>
<para>
Users who use single switches may prefer to start <application>On-Screen Keyboard</application> in automatic scanning mode. The following line starts <application>On-Screen Keyboard</application> in automatic scanning mode when the user presses the switch on an alternative access device for more than four seconds:
</para>
<para>
<literal>&lt;Switch&gt;1 4000 5000 gok --login --accessmethod=automaticscanning
--scan-action=switch1 --select-action=switch1</literal>
</para>
<para>
For information about the <application>On-Screen Keyboard</application> operating modes, see the online help for <application>On-Screen Keyboard</application>.
</para>
</section>

<section id="sysadmin-32">
<title>Starting On-Screen Keyboard Using a Motion-Only Gesture</title>
<para>
You can define gestures that involve only the motion of a pointing device such as a mouse, or an alternative pointing device, such as a head pointer or trackball. The syntax of the gesture does not change depending on whether you are using a mouse or an alternative pointing device. Edit the 
<filename>AccessKeyMouseEvents</filename> 
file to associate motion gestures with assistive technologies.
</para>
<para>
If the <literal>dwellmouselistener</literal> GtkModule is loaded, alternative pointing devices are temporarily latched to the core pointer. This means that if the user moves the alternative pointing device, the on-screen pointer moves.
</para>
<para>
For example, the following line starts 
<application>On-Screen Keyboard</application> in dwell mode when the user moves the on-screen pointer from inside the login dialog through the top edge, back into the dialog through the top edge, out of the dialog 
through the left edge, back into the dialog through the left edge, and similarly through the bottom and right edges of the dialog in a cross pattern:
</para>
<para>
<literal>TTLLBBRR O 10000 gok --login --access-method=dwellselection
--input-device=MOUSE[3]</literal>
</para>
<para>
Note that the <literal>--input-device</literal> parameter specified in the gesture must match the name of the extended user input device, such as a head pointer or trackball, as specified in <filename>/etc/X11/XF86Config</filename>.
</para>
</section>
</section>

<section id="sysadmin-33">
<title>Additional Requirements for Accessible Login</title>
<para>
To enable the Accessible Login feature to use 
alternative pointing devices and switch devices such as sip-and-puff switches, wheelchair-mounted switches or trackballs, you might need to modify your X server 
system configuration to recognize these devices. You can use most devices that emulate mouse buttons with the Accessible Login feature and <application>On-Screen Keyboard</application>, including USB single switches and mouse-like pointing devices.
</para>
<note>
<para>
You should not configure an alternative input device to control the primary on-screen pointer. This might result in undesirable behavior or cause situations from which 
the user of the alternate input device cannot recover without using the primary keyboard or mouse. To prevent this problem, remove any occurrences of the attributes 
<literal>SendCore</literal> or <literal>AlwaysCore</literal> from any of the 
<literal>InputDevice</literal> lines in the X Server configuration file.

Since there are so many applications that you can use in the GNOME Desktop, this manual does not describe all the custom keyboard shortcuts that you can use with each individual application. However, the basic keyboard shortcuts are common to many applications.
