<title>Introduction to Accessibility</title>
<indexterm>
<primary>Section 508</primary>
</indexterm>
<para>
This chapter introduces you to accessibility in the GNOME Desktop.
</para>
<para>
All software products should incorporate accessibility features to enable people with disabilities to use the software easily and efficiently. Recent legislation such as Section 508 of the U.S. Rehabilitation Act
heightens awareness of the need to provide accessible software.
</para>
<para>
The GNOME Desktop is easy to use and incorporates many accessibility features. Every supported application and utility in the GNOME Desktop is designed with accessibility and usability in mind. Users with physical disabilities such as low vision or impaired motor skills can use all of the functionality of the GNOME Desktop thanks to the customization tools that are available. These customization tools enable you to fine-tune the appearance and behavior of the desktop.
</para>
<para>
The ability to easily customize the GNOME Desktop contributes greatly to the accessibility of the desktop. This guide describes the various options available to
meet your particular needs.
</para>

<section>
<title>Essential Keyboard Commands</title>
<para>
Before moving forward, be sure you are familiar with these essential GNOME commands:
</para>
<para>
<keycombo><keycap>Alt</keycap><keycap>F1</keycap></keycombo> [Debian] - display and activate the GNOME Desktop menu bar. This grants access to the <guimenu>Applications</guimenu>, <guimenu>Places</guimenu> and <guimenu>System</guimenu> menu bar items.
</para>
<note>
<para>
For Solaris and Windows systems, this key is <keycombo><keycap>Ctrl</keycap><keycap>Esc</keycap></keycombo>.
</para>
</note>
<para>
<keycombo><keycap>Alt</keycap><keycap>F2</keycap></keycombo> or <keycombo><keycap>Meta</keycap><keycap>R</keycap></keycombo> - summons the <application>Run</application> dialog, where you can issue terminal commands with or without parameters. If a file needs to be passed as one of these parameters, use the <guilabel>Run With File</guilabel> button to easily locate the file needed. This dialog also presents an alternate list of known applications which may be easier to navigate than the Debian system desktop menu (<keycombo><keycap>Alt</keycap><keycap>F1</keycap></keycombo>) approach.
</para>
<note>
<para>
For Solaris systems, this key is <keycombo><keycap>Meta</keycap><keycap>R</keycap></keycombo> (as with Microsoft Windows). A meta- or super-key is an OS-logo shift key.
</para>
</note>
<para>
<keycap>Tab</keycap> and <keycombo><keycap>Shift</keycap><keycap>Tab</keycap></keycombo> - move focus within an application between controls; use <keycap>Tab</keycap> to cycle forward through controls and <keycombo><keycap>Shift</keycap><keycap>Tab</keycap></keycombo> to cycle backwards. Controls are any user-interactive element that you can manipulate, such as buttons, drop-down lists, text fields, etc. <keycombo><keycap>Ctrl</keycap><keycap>Tab</keycap></keycombo> and <keycombo><keycap>Shift</keycap><keycap>Ctrl</keycap><keycap>Tab</keycap></keycombo> are used instead where <keycap>Tab</keycap> and <keycombo><keycap>Shift</keycap><keycap>Tab</keycap></keycombo> are reserved for use by the focused control.
</para>
<para>
<keycombo><keycap>Alt</keycap><keycap>Tab</keycap></keycombo> and <keycombo><keycap>Shift</keycap><keycap>Alt</keycap><keycap>Tab</keycap></keycombo> - switches between currently running applications. If you have multiple programs running, use <keycombo><keycap>Alt</keycap><keycap>Tab</keycap></keycombo> to cycle forward through the applications and <keycombo><keycap>Shift</keycap><keycap>Alt</keycap><keycap>Tab</keycap></keycombo> to cycle backwards. <keycombo><keycap>Alt</keycap><keycap>Esc</keycap></keycombo> and <keycombo><keycap>Shift</keycap><keycap>Alt</keycap><keycap>Esc</keycap></keycombo> also cycle between applications, but without an application preview window.

<title>Enabling Accessible Login</title>
<indexterm>
<primary>GDM</primary>
</indexterm>
<para>
In order to use the accessibility support for GNOME, the accessibility infrastructure must be enabled. To enable GNOME accessibility features from the command line, type the following command and then log out:
</para>
<para>
<userinput>gconftool-2 --set "/desktop/gnome/interface/accessibility" --type boolean "True"</userinput>
</para>
<para>
To enable GNOME accessibility features from a GUI, run the <menuchoice>
<guimenuitem>System</guimenuitem>
<guimenuitem>Preferences</guimenuitem>
<guimenuitem>Assistive Technology</guimenuitem>
</menuchoice> command from the top level menu.  Select the <guilabel>"Enable assistive technologies"</guilabel> checkbox and then press the <guilabel>"Close and Log Out"</guilabel> button.
</para>
<para>
The next time you log in, assistive technology support will be enabled for the desktop.
</para>
<para>
To configure GDM by using the GUI (the preferred method), perform the following steps:
</para>
<orderedlist>
<listitem>
<para>
Log in as the <literal>root</literal> user.
</para>
</listitem>
<listitem>
<para>
Run <application>gdmsetup</application> from a terminal; you may be advised to reboot after exiting the application.
</para>
</listitem>
</orderedlist>
<para>
To configure GDM if you cannot access the GUI environment, you will need to navigate the file system and modify files:
</para>
<orderedlist>
<listitem>
<para>
Log in as the <literal>root</literal> user.
</para>
</listitem>
<listitem>
<para>
Open the file <filename>/etc/X11/gdm/custom.conf</filename>

</listitem>
<listitem>
<para>
Search the file for the following line:
</para>
<para>
<literal>#AddGtkModules=false</literal>
</para>
<para>
and replace the line with the following:
</para>
<para>
<literal>AddGtkModules=true</literal>
</para>
<para>
This step enables the GtkModules.
</para>
</listitem>
<listitem>
<para>
Search the file for the following line:
</para>
<para>
<literal>
#GtkModulesList=gail:atk-bridge:dwellmouselistener:keymouselistener

</para>
<para>
and delete the <literal>#</literal> from the start of the line so that the line reads:
</para>
<para>
<literal>
GtkModulesList=gail:atk-bridge:dwellmouselistener:keymouselistener
</literal>
</para>
<note>
<para>
The above lines must be displayed as single lines in the <filename>custom.conf</filename> file without line breaks. The formatting of this guide may display the lines as being longer than two lines.
</para>
</note>
<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>
<itemizedlist>
<listitem>
<para>
If you need to use the <application>
Screen Reader and Magnifier</application>, include <literal>gail</literal> and <literal>atk-bridge</literal>.
</para>
</listitem>
<listitem>
<para>
If you need to use a pointing device without buttons or switches, include <literal>gail</literal>, <literal>atk-bridge</literal> and 
<literal>dwellmouselistener</literal>. 
</para>
</listitem>
<listitem>
<para>
If you use pointing devices with switches, alternative physical keyboards, or switch and button devices, include <literal>keymouselistener</literal>.
</para>
</listitem>
<listitem>
<para>
<application>On-Screen Keyboard</application> can operate without <literal>gail</literal> and <literal>atk-bridge</literal>, but with a reduced feature set.

<para>
For optimum accessibility, include 
<literal>gail</literal> and <literal>atk-bridge</literal>.
</para>
</listitem>
<listitem>
<para>
Save the <filename>/etc/X11/gdm/custom.conf</filename> file.
</para>
<note>
<para>
If you make any changes to the 
<filename>/etc/X11/gdm/custom.conf</filename> file after you enable GDM, you can execute the following command to restart GDM and activate the changes:
</para>
<para>
<command>gdm-restart</command>

<listitem>
<para>
Restart your system.
</para>
</listitem>
</orderedlist>
<para>
<application>Xserver</application> is required for all distributions; for Linux and OpenSolaris, it should be <application>Xorg</application>. You can find them in both <filename>/etc/X11</filename> and <filename>/usr/bin</filename>. Generally for Linux there will be a symbol link in <filename>/etc/X11/X</filename> and it is always linked to the binary <filename>Xorg</filename> in <filename>/usr/bin/Xorg</filename>. For OpenSolaris, you can find this process with the command <userinput>ps -ef | grep X</userinput>.
</para>
<para>
To enable or disable <application>Xorg</application> extensions, you can edit the file
<filename>/etc/X11/xorg.conf</filename> and add the following parameters to enable different
extensions:
</para>
<programlisting>
<computeroutput>

<title>Starting Assistive Technologies at Login</title>
<indexterm>
<primary>gestures</primary>
</indexterm>
<para>
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 GDM configuration files: 
</para>
<itemizedlist>
<listitem>
<para>
<filename>
/etc/X11/gdm/modules/AccessKeyMouseEvents
</filename>

</itemizedlist>
<note>
<para>
If you modify these files, you must restart your system before the changes take effect.
</para>
</note>
<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
</filename> file without line breaks. The formatting of this guide might display the examples in the following sections across multiple lines. 
</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 lines enable you to press and hold <keycombo><keycap>Ctrl</keycap><keycap>S</keycap></keycombo> or <keycombo><keycap>Ctrl</keycap><keycap>M</keycap></keycombo> for one second to either start speech or magnification:

</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:

<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.

<title>Low Vision or Blindness</title>
<para>
From low vision to blindness, the range of visual limitations is broad. Symptoms of low vision include dimness, haziness, extreme far-/near-sightedness, color blindness, and tunnel vision, among others. People with these disabilities are concerned with being able to see text or images on a computer screen and being able to perform tasks that 
require eye-hand coordination, such as moving a computer mouse. Text size and color can make a big difference in legibility for people with low vision.

<para>
A theme is a group of coordinated settings that specifies how a desktop component or a group of desktop components appears. You can use themes to modify and control the appearance of the desktop in a consistent manner. When you apply a theme, the system modifies many desktop components simultaneously to achieve the desired effect. For example, if you apply a theme that increases the font size across the desktop, the theme also modifies the size of panels and icons on the desktop for optimum compatibility with the font size. Some themes have suggested font settings that may optionally be auto-set; in addition, most colors within a theme can be customized.
</para>
<para>
A theme contains settings that affect different parts of the desktop: 
</para>
<variablelist>
<varlistentry>

The controls setting for a theme determines the visual appearance of all windows, applications, panels, and panel applications. The controls setting also determines the visual appearance of the GNOME-compliant interface items that appear on windows, applications, panels, and panel applications such as menus, icons, and buttons. Some of the control options that are available in the desktop are designed for special accessibility needs.

<section>
<title>Introduction to Orca</title>
<section>
<title>What is Orca?</title>
<para>
Orca is a flexible, extensible, and powerful assistive technology for people with visual impairments. Using various combinations of speech synthesis, braille and magnification, Orca helps provide access to applications
and toolkits that support the AT-SPI (e.g., the GNOME Desktop). <application>Orca</application> is also free open source software.
</para>
</section>

<section>
<title>Why the name Orca?</title>
<para>
One of the first DOS screen readers was Flipper, made by Omnichron Corporation in Berkeley, CA. It was named Flipper in part because the blind wife of the programmer 
envisioned computers as being programmed by flipping switches (an accurate image of a bygone era). Then came another DOS screen reader, this one from Henter-Joyce in 
Florida - "Jobs Access With Speech" (or JAWS). And so on....
</para>
<para>
Although no obvious connection exists between blindness and creatures from the sea, there is certainly a naming tradition for screen-reader software. Hence <application>Orca</application>, which is a lot tougher-sounding than Nemo, Ariel, Willy, or Mr. Limpet.
</para>
</section>

<section>
<title>What's the schedule?</title>
<para>
<application>Orca</application> is part of the GNOME platform and <application>Orca</application>'s releases are coupled with the releases of the GNOME platform.

(<ulink url="http://mail.gnome.org/archives/orca-list">Archives</ulink>).
</para>
</section>

<section>
<title>Is braille supported?</title>
<para>
Yes! Braille is supported via BrlTTY and it is tightly integrated with Orca. BrlTTY offers support for nearly every refreshable braille display known to man.
</para>
</section>

<section>
<title>Is contracted braille supported?</title>
<para>
Yes, <application>Orca</application> fully supports contracted braille output.
</para>
</section>

<section>
<title>What voices are available?</title>
<para>
<application>Orca</application> provides interfaces to both <userinput>gnome-speech</userinput> and <userinput>emacspeak</userinput> speech services. As such, the available voices for <application>Orca</application> are only restricted by the speech engines supported by the available speech services. For free speech engines, you typically have a choice of the eSpeak, Festival, and FreeTTS speech engines. For commercial engines, you have a choice of 
additional engines such as Fonix DECtalk, Loquendo, Eloquence, Cepstral and IBMTTS, with others on the way. Periodically check the <userinput>gnome-speech</userinput> package for more progress in this area.
</para>
</section>

<section>
<title>What languages are supported?</title>
<para>
The <ulink url="http://l10n.gnome.org/teams">
GNOME translation teams</ulink> are composed of many passionate volunteers from around the world. These teams do a great job and keep an up-to-date status report. See the <ulink url="http://l10n.gnome.org/module/orca">
Orca translation status page</ulink> for the large number of languages into which <application>Orca</application> has been translated.
</para>
<para> 
Note: support for a language also depends on 
the speech synthesis engine also supporting the same language.
</para>
</section>

<section>
<title>How well does magnification work?</title>
<para>
<application>Orca</application> currently uses the <userinput>gnome-mag</userinput> 
magnification service. <userinput>gnome-mag</userinput> has incorporated support for smoother full-screen magnification, which 
relies upon newer extensions in the X Window System server. These extensions do not always function well on all platforms, so smooth full-screen magnification may not always work.
</para>

<section id="enable-orca">
<title>Enabling Orca</title>
<para>
For a text-only guided setup, open a Run dialog with <keycombo><keycap>Alt</keycap><keycap>F2</keycap></keycombo> or <keycombo><keycap>Meta</keycap><keycap>R</keycap></keycombo> and use the command <userinput>orca --text-setup</userinput> <keycap>Enter</keycap>.
</para>
<para>
The first time <application>Orca</application> is launched you will be asked a few questions:
</para>
<para>
First you will be presented with a list of languages to choose from; there are currently about 64 languages and dialects supported. Most of this list will scroll off the screen, so you may have to use the terminal's scrollbar to view earlier parts of the list. Type in the number of your language choice (e.g., 7 for American English) and press <keycap>Enter</keycap>.  You do not need to wait for the entire list to be spoken, and Orca attempts to make your default language the first choice (choice 1).
</para>
<para>
You are next asked to set <guilabel>Echo By Word</guilabel>. This option instructs <application>Orca</application> to speak words as you finish typing them. Type <keycap>y</keycap> or <keycap>n</keycap> and press <keycap>Enter</keycap>.
</para>
<para>
The next item is <guilabel>Key Echo</guilabel>. This option will speak all keys as they are pressed. Type <keycap>y</keycap> or <keycap>n</keycap> and press <keycap>Enter</keycap>.
</para>
<para>
Now select your desired keyboard layout; generally, you will want to choose the layout that matches your keyboard type - 1 for Desktop or 2 for Laptop. This choice will determine what key will act as the <application>Orca</application> modifier key. The Desktop layout uses <keycap>Insert</keycap> while the Laptop layout uses <keycap>Caps Lock</keycap>. A system, host, shift or modifier key is one which is used in conjunction with other keys, enabling keyboard access to most program functions.
</para>
<para>
Next, specify if you require braille output. This functionality assumes a BrlTTY-compatible device is available. Type <keycap>y</keycap> or <keycap>n</keycap> and press <keycap>Enter</keycap>.  Note that you can usually just enter <keycap>y</keycap> here; Orca will recover gracefully and function even if it cannot find BrlTTY.
</para>
<para>
Lastly, indicate whether you want an on-screen braille output monitor. This is mostly for developers who need to verify BrlTTY output, but may also be useful in other situations, such as visually diagnosing or verifying braille output.

<para>
The <application>Orca</application> main window provides you with a graphical way to display the <application>Orca</application> Configuration GUI (also accessible with <keycombo><keycap>Orca_Modifier</keycap><keycap>Space</keycap></keycombo>, where Orca_Modifier is <keycap>Insert</keycap> when you use the Desktop Keyboard Layout (<xref linkend="orca-desktop-keys"/>) and <keycap>Caps_Lock</keycap> when you use the Laptop Keyboard Layout (<xref linkend="orca-laptop-keys"/>)). The main window also provides a <guibutton>Quit</guibutton> option, also available with <keycombo><keycap>Orca_Modifier</keycap><keycap>Q</keycap></keycombo>). Many users do not like the <application>Orca</application> main window because it shows up in the window manager's tab order when you press <keycombo><keycap>Alt</keycap><keycap>Tab</keycap></keycombo> to switch windows. By deselecting the "Show Orca main window" button, you can tell <application>Orca</application> to not show the <application>Orca</application> main window.

<section>
<title>Disable gksu keyboard grab</title>
<para>
When running commands from the launch menu, many distributions use an application known as <application>gksu</application> to authorize the user to run these commands; <application>gksu</application> is the GUI that asks you for your password. When it runs, <application>gksu</application> enables what is known as a "keyboard grab," which is a feature to prevent keyboard actions from going to any other application on the desktop, including <application>Orca</application>.  The result of a keyboard grab is that <application>Orca</application> will not receive any keyboard events, preventing <application>Orca</application> from functioning normally.
</para>
<para>
By selecting the "Disable gksu keyboard grab" button, you will turn off the keyboard grab behavior, allowing <application>Orca</application> to function normally with system administration applications.
</para>
<note>
<para>
The keyboard grab is a security attempt by <application>gksu</application> to prevent nefarious applications from "sniffing" the keyboard and grabbing secret information.  Please be advised that disabling the gksu keyboard grab feature can expose you to such nefarious behavior. If you do not feel comfortable with this, you can always use the root account for system administration purposes. To do so, you need to enable the root account for login, and then logout and log back in as root whenever you want to perform a system administration command.
</para>
</note>
</section>

<section>
<title>Present tooltips</title>
<para>
When checked, this option will tell <application>Orca</application> to present information about tooltips when they appear as the result of mouse hovering. Specific actions to force tooltips to appear, such as pressing <keycombo><keycap>Ctrl</keycap><keycap>F1</keycap></keycombo> when an object has focus, will always result in tooltips being presented, regardless of this setting.
</para>
</section>

<section>
<title>Speak object under mouse</title>
<para>
When checked, this option will tell <application>Orca</application> to present information about the object under the mouse when you move it around the screen. Note that this can cause <application>Firefox</application> and <application>Thunderbird</application> versions 2.x and earlier to crash; this is not a problem with <application>Firefox</application> and <application>Thunderbird</application> versions 3.x and later.
</para>
</section>

<para>
The speech page allows you to customize how <application>Orca</application> uses speech synthesis.
</para>

<section>
<title>Enable speech</title>
<para>
The first control of note on the speech page is the "enable speech" check box. This check box toggles whether or not <application>Orca</application> will make use of a speech synthesizer. This option, along with the ability to enable braille and enable magnifier support, allow <application>Orca</application> to be tailored to meet the needs of a wide variety of users.
</para>
</section>

<section>
<title>Speech System and Speech Synthesizer</title>
<para>
The next two controls deal with selecting the speech system and synthesizer. <application>Orca</application> provides support for a growing number of speech systems. At the time of this writing, these include GNOME-speech, Emacspeak, and an experimental backend for Speech Dispatcher.  Depending upon how your machine is configured, you may have all or none of these options.  Typically, you will have just GNOME-speech.
</para>
<para>
First, determine which speech system you would like to use - GNOME-speech works best at this time. After making your selection, tab to the speech synthesizer combo box and choose from the list of available synthesizers.
</para>
</section>

<section>
<title>Voice Settings</title>
<para>
If your synthesizer supports it, <application>Orca</application> can utilize multiple voices in order to identify special cases within an application, such as hyperlinks or upper case text. The voice settings and person combo boxes can be adjusted to customize these settings to your liking. For example, assume you were using Fonix DECtalk and wanted the Betty voice to denote upper case. To accomplish this, you could do the following:
</para>
<procedure>
<step>
<para>
Tab to the voice settings combo box, and down arrow until the upper case voice is selected.
</para>
</step>
<step>
<para>
Tab to the person combo box, and down arrow to choose the Betty voice.
</para>
</step>
</procedure>
<para>
The next three sliders in the tab order allow adjustment of the synthesizer's rate, pitch and volume, respectively.
</para>
</section>

<section>
<title>Nivel de puntuación</title>
<para>
The punctuation level radio button group is used to adjust the amount of punctuation spoken by the synthesizer. The available levels are None, Some, Most and All.
</para>
</section>

<section>
<title>Cantidade de información</title>
<para>
The verbosity setting determines the amount of information that will be spoken in certain situations. For example, if it is set to verbose, the synthesizer will speak shortcut keys for items in pull down menus. When it is set to brief, these shortcut keys are not announced.
</para>
</section>

<section>
<title>Lectura da fila da táboa</title>
<para>
The table row speech option determines the way in which <application>Orca</application> will read items within tables. The available settings are "speak current row" or "speak current cell". The ability to adjust this behavior can be useful in many situations.  For example, consider the process of browsing email messages in <application>Evolution</application>. In this instance it may be preferable to set table speech to "speak current row" so that while arrowing through the list of messages all relevant info, such as the sender, subject, and whether the message has attachments, is read automatically. While the current row setting is active, it is still possible to read individual cells by using the left and right arrows.
</para>
<note>
<para>
You can quickly toggle this behavior by pressing <keycombo><keycap>Orca_Modifier</keycap><keycap>F11</keycap></keycombo>.
</para>
</note>
</section>

<section>
<title>Ler as liñas en branco</title>
<para>
Some users desire to hear "blank" when navigating to a blank line in a document.  Other users do not. If the "speak blank lines" check box is selected, <application>Orca</application> will speak blank lines.
</para>
</section>

<section>
<title>Speak multicase strings as words</title>
<para>
When working with code, one often comes across a "word" consisting of several words with alternating case, such as "MultiCaseString." Speech synthesizers do not always pronounce such multicase strings correctly. Checking the <guilabel>Speak multicase strings as words</guilabel> checkbox will cause <application>Orca</application> to break a word like "MultiCaseString" into separate words ("Multi," "Case," and "String") prior to passing it along to the speech synthesizer.
</para>
</section>

<section>
<title>Ler as mensaxes do tutorial</title>
<para>
When moving from component to component in an interface, this option will provide spoken tutorial messages for how to work with the component.
</para>
</section>

<section>
<title>Speak object mnemonics</title>
<para>
This option will cause <application>Orca</application> to announce the mnemonic associated with the object with focus (such as "Alt O" for the <guilabel>OK</guilabel> button).
</para>
</section>

<section>
<title>Break speech into chunks between pauses</title>
<para>
Depending on the enabled speech settings, <application>Orca</application> may have quite a bit to say about a particular object such as its name, its role, its state, its mnemonic, its tutorial message, and so on. Checking the <guilabel>Break speech into chunks between pauses</guilabel> checkbox will cause <application>Orca</application> to insert brief pauses in between each of these pieces of information.
</para>
</section>

<section>
<title>Speak child position</title>
<para>
Checking the <guilabel>Speak child position</guilabel> checkbox will cause <application>Orca</application> to announce the position of the focused item in menus and lists (e.g. "9 of 16").
</para>
</section>

<section>
<title>Speak Indentation and Justification</title>
<para>
When working with code or editing other documents it is often desirable to be aware of justification and indentation. Selecting the <guilabel>Speak indentation and justification</guilabel> check box will cause <application>Orca</application> to provide this information.
</para>
</section>

<section>
<title>Speak Progress Bar Updates</title>
<para>
If this setting is enabled, <application>Orca</application> will periodically announce the status of progress bars. How often the announcement is made is determined by the value chosen in the update interval spin button. Note that this spin button is only available if the <guilabel>Speak progress bar updates</guilabel> checkbox has been checked.
</para>
</section>

<section>
<title>Restrict progress bar updates to</title>
<para>
This setting controls which progress bars should be spoken, assuming the <guilabel>Speak progress bar updates</guilabel> checkbox has been checked. The choices are All, Application, and Window. Choosing All will result in <application>Orca</application> speaking updates for all progress bars, regardless of where the progress bars are located. Choosing Application will result in <application>Orca</application> speaking updates from progress bars in the active application, even if they are not in the active window. Choosing Window will result in <application>Orca</application> only speaking updates for progress bars in the active window. The default value is Application.
</para>
</section>

<section>
<title>Say All By</title>
<para>
This combo box allows you to specify whether the "say all" functionality of <application>Orca</application> speaks by sentence or line.  See the Desktop Keyboard Layout (<xref linkend="orca-desktop-keys"/>) and Laptop Keyboard Layout (<xref linkend="orca-laptop-keys"/>) for how to invoke the "say all" functionality).

<section>
<title>Enable Braille Support</title>
<para>
The first control on the braille page is the "Enable braille support" check box. This check box toggles whether or not <application>Orca</application> will make use of a braille display. This option, along with the ability to enable braille and enable magnifier support, allow <application>Orca</application> to be tailored to meet the needs of a wide variety of users. By default, this check box is enabled. If BrlTTY is not running, <application>Orca</application> will recover gracefully and will not communicate with the braille display. If you configure BrlTTY later on, you need to restart <application>Orca</application> in order for it to use braille.
</para>
</section>

<section>
<title>Enable Braille Monitor</title>
<para>
<application>Orca</application>'s braille monitor provides an on-screen representation of what takes place on the braille display. This feature is mostly for demonstration purposes, but is also useful for <application>Orca</application> developers who do not have access to a braille display.
</para>
</section>

<section>
<title>Abbreviated Role Names</title>
<para>
The "Abbreviated role names" check box determines the manner in which role names are displayed and can be used to help conserve real estate on the braille display. The "Abbreviated role names" option can be better understood if we consider the following example. Let us assume that a slider had focus, and that the abbreviated role names box was not checked. In this case, the word "slider" would be shown on the display, to reflect the fact that the current control was indeed a slider. If the abbreviated role names box were checked, the word "slider" would be abbreviated to "sldr".
</para>
</section>

<section>
<title>Disable end of line symbol</title>

<para>
The key echo page allows you to specify the behavior of <application>Orca</application> when pressing keys on the page and whether words are spoken as you complete them.
</para>

<section>
<title>Enable Key Echo</title>
<para>
The first control on the key echo page is the "Enable key echo" check box. When this box is selected, seven additional check boxes become available. These are: "Enable alphanumeric and punctuation keys", "Enable modifier keys", "Enable locking keys", "Enable function keys", "Enable action keys", "Enable navigation keys", and "Enable non-spacing diacritical keys".
</para>
<para>
The alphanumeric and function key groups are relatively self explanatory.
</para>
<para>
Modifier keys are those such as <keycap>Shift</keycap>, <keycap>Ctrl</keycap>, and <keycap>Alt</keycap>.
</para>
<para>
Locking keys include <keycap>Caps Lock</keycap>, <keycap>Scroll Lock</keycap> and <keycap>Num Lock</keycap>.
</para>
<para>
The action keys group consists of keys that perform some logical action, such as <keycap>Backspace</keycap>, <keycap>Return</keycap> and <keycap>Tab</keycap>.
</para>
<para>
The navigation keys group include the four arrow keys as well as any key combination in which the Orca Modifier key is being held down. The latter is designed to prevent <application>Orca</application> from echoing flat review commands.
</para>
<para>
Non-spacing diacritical keys are those "dead keys" used to generate accented letters.
</para>
</section>

<section>
<title>Enable Echo by Character</title>
<para>
The next toggle on the key echo page is the "Enable echo by character" check box, used to echo the character you just typed. While echo by character seems quite similar to the key echo of alphanumeric and punctuation keys, there are important differences, especially with respect to accented letters and other symbols for which there is no dedicated key. Key echo causes <application>Orca</application> to announce what you just pressed; character echo causes it to announce what was inserted. The "Echo by character" control is always available, regardless of whether any of the key echo options are checked.
</para>
</section>

<section>
<title>Enable Echo by Word</title>
<para>
The next toggle on the key echo page is the "Enable echo by word" check box, used to echo the word you just typed. The "Echo by word" control is always available, regardless of whether any of the key echo options are checked.
</para>
</section>

<section>
<title>Enable Echo by Sentence</title>
<para>
The last toggle on the key echo page is the "Enable echo by sentence" check box, used to echo the sentence you just typed. The echo by sentence control is always available, regardless of whether any of the key echo options are checked.
</para>
<para>
In summary, the key echo scheme can offer a great deal of flexibility. For example, one user might choose to enable all key echo options, while another might prefer to use word echo, but only have locking keys announced.

The first control on the key bindings page allows you to examine which key (or keys) acts as the "<application>Orca</application> modifier." The <application>Orca</application> modifier is the key that you press and hold in conjunction with other keys to give commands to <application>Orca</application>. For  desktop keyboards, the Orca modifier defaults to <keycap>Insert</keycap>. For laptop keyboards, the <application>Orca</application> modifier defaults to the <keycap>Caps Lock</keycap> key.  See the Desktop Keyboard Layout (<xref linkend="orca-desktop-keys"/>) and Laptop Keyboard Layout (<xref linkend="orca-laptop-keys"/>) sections for the default values.

<section>
<title>Key Bindings Table</title>
<para>
The key bindings table provides a list of <application>Orca</application> operations and the keys that are bound to them.
</para>
<para>
The "Function" column header is a description of the <application>Orca</application> operation to be performed.
</para>
<para>
The "Key Binding" header is the primary way to invoke the function from the keyboard. Note that the function description may include the word "Orca". This indicates that the <application>Orca</application> modifier key should be held down along with the other keys.
</para>
<para>
The "Alternate" header provides an alternate mechanism for invoking the function from the keyboard.
</para>
<para>
To modify either the "Key Binding" or the "Alternate" bindings, arrow to the cell and press <keycap>Return</keycap>. Then, press a key combination and press <keycap>Return</keycap> to confirm the new combination. When you do so, the new keystroke will be saved and the check box in the last column (the "Modified" column) will indicate that the key binding has been modified.
</para>
<para>
To undo a modified keybinding, merely arrow to the modified column, uncheck the checkbox, and press the "Apply" button <keycombo><keycap>Alt</keycap><keycap>A</keycap></keycombo>.

These are commands which we feel will be very useful for some users, but not needed by most users. Rather than "use up" a keystroke for such commands, we have left them unassigned.  You can assign a keystroke to any of these unbound commands by following the procedure outlined above. In addition, you can unbind any bound command in a similar fashion: press <keycap>Return</keycap> to edit the keybinding, and when prompted for the new keybinding, press <keycap>Delete</keycap> or <keycap>Backspace</keycap>. You will be told that the key binding has been removed. Press <keycap>Return</keycap> to confirm.

Sometimes your speech synthesizer just doesn't say the right thing for a given string. You might prefer to hear "laughing out loud" rather than "LOL." Or there may be a name or a technical term which the synthesizer mispronounces. The pronunciation page is where you can add, edit, and delete <application>Orca</application>'s pronunciation dictionary entries. Because the pronunciation page is also part of the application-specific settings dialog that's started when you give a particular application focus and type <keycombo><keycap>Orca_Modifier</keycap><keycap>Ctrl</keycap><keycap>Space</keycap></keycombo>, you can customize your entries on an as-needed basis for each application you use.

<para>
<application>Orca</application> will speak known text attribute information about an object when you press <keycombo><keycap>Insert</keycap><keycap>F</keycap></keycombo> (desktop layout) or <keycombo><keycap>Caps_Lock</keycap><keycap>F</keycap></keycombo> (laptop layout). Because the number of text attributes is large, and not everyone cares about every attribute, the "Text Attributes" tab of the configuration
GUI allows you to customize which text attributes <application>Orca</application> will present.
</para>
<para>
On this tab is a text attribute list, where each row consists of four columns:
</para>
<itemizedlist>
<listitem>
<para>
The name of the text attribute.
</para>
</listitem>
<listitem>
<para>
A checkbox which the user can set to indicate whether this text attribute should be spoken or not.
</para>
</listitem>
<listitem>
<para>
A checkbox which the user can set to indicate whether this text attribute should be "underlined" on the braille display.
</para>
</listitem>
<listitem>
<para>
An editable "Present unless" string value. By default, not all text attributes will have this set. If present, what it means (assuming the user wants this text attribute presented) is that the value of the attribute will only be presented if it is <emphasis>not</emphasis> this value.
</para>
<para>
For example, by default the "underline" text attribute has a value of "none." If the user has this attribute checked and the user types
<keycombo><keycap>Orca_Modifier</keycap><keycap>F</keycap></keycombo> and the text in question is not underlined, then this
attribute is not spoken. If you always want this attribute to be spoken irrespective of whether the text is underlined, then the
attribute should be checked and the "Present unless" value cleared.
</para>
</listitem>
<listitem>
<para>
There is also a <guibutton>Reset</guibutton> button (<keycombo><keycap>Alt</keycap><keycap>R</keycap></keycombo>) which will set the list values back to their initial state when the dialog was first displayed.
</para>
</listitem>
</itemizedlist>
<para>
When you initially display the text attribute pane, all your checked attributes are put at the top of the list. They are given in the order that they will be spoken and brailled.

</para>
<itemizedlist>
<listitem>
<para>
<guibutton>Move to top</guibutton> (<keycombo><keycap>Alt</keycap><keycap>T</keycap></keycombo>) - moves the selected attribute to the top of the list.

<listitem>
<para>
<guibutton>Move down one</guibutton> (<keycombo><keycap>Alt</keycap><keycap>D</keycap></keycombo>) - moves the selected attribute down one row.

<guibutton>Move to bottom</guibutton> (<keycombo><keycap>Alt</keycap><keycap>B</keycap></keycombo>) - moves the selected attribute to the bottom of the list.
</para>
</listitem>
</itemizedlist>
<para>
Beneath these push buttons is the Braille Indicator group of radio buttons. Here you can select the cell or cells to be used to indicate text which has at least one of the specified attributes. Your choices are:

You can get a complete list of available keyboard commands by visiting the <guilabel>Key Bindings</guilabel> page of the <application>Orca</application> Configuration GUI (<xref linkend="orca-keybindings-page"/>). To bring up the <application>Orca</application> Configuration GUI, press <keycombo><keycap>Orca_Modifier</keycap><keycap>Space</keycap></keycombo>, where <userinput>Orca_Modifier</userinput> is the <keycap>Insert</keycap> key for the <link linkend="orca-desktop-keys">desktop layout</link> and the <keycap>Caps_Lock</keycap> key for the <link linkend="orca-laptop-keys">laptop layout</link>. Note that you can also enter <application>Orca</application>'s "learn mode" while running <application>Orca</application> by pressing <keycombo><keycap>Orca_Modifier</keycap><keycap>H</keycap></keycombo>. When in learn mode, <application>Orca</application> will intercept all keyboard and braille input events and tell you what the effect would be.  To exit learn mode, press the <keycap>Escape</keycap> key.
</para>
<note>
<para>
<application>Orca</application> provides additional commands for some applications, such as <application>Firefox</application>.  To get the list of additional commands for an application, press <keycombo><keycap>Ctrl</keycap><keycap>Orca_Modifier</keycap><keycap>Space</keycap></keycombo> when that application has focus.

WARNING: the MouseKeys functionality of AccessX can interfere with the <application>Orca</application> modifier key (see <ulink url="http://bugzilla.gnome.org/show_bug.cgi?id=548169">bug 548169</ulink>), resulting in odd behavior. In particular, MouseKeys uses the <keycap>KP_Insert</keycap> key to emulate a mouse button press. When enabled, MouseKeys can conflict with <keycap>KP_Insert</keycap> as the <application>Orca</application> modifier, resulting in what appears to be a stuck <application>Orca</application> modifier key.  As an alternative, you can use the <link linkend="orca-laptop-keys">laptop key bindings</link>, which avoids the keypad for <application>Orca</application> commands. If you accidentally enabled MouseKeys, you can disable it via the <application>gnome-keyboard-properties</application> application.

<para>
The above commands apply when working with objects as well as when working with text.  For example, if the flat review cursor were positioned on a menu bar, pressing the "read current line" command would speak the names of all visible menus. Similarly, pressing the "read next word" command would speak the object to the right of the flat review cursor on the same line, or move flat review to the next line if no more objects were found.

<para>
The above commands apply when working with objects as well as when working with text.  For example, if the flat review cursor were positioned on a menu bar, pressing the "read current line" command would speak the names of all visible menus. Similarly, pressing the "read next word" command would speak the object to the right of the flat review cursor on the same line, or move flat review to the next line if no more objects were found.

<title>Accessible Applications</title>
<para>
<application>Orca</application> is designed to work with applications and toolkits that support the Assistive Technology Service Provider Interface (AT-SPI). This includes the GNOME Desktop and its bundled applications: OpenOffice, Firefox, and the Java platform. Some applications work better than others, however, and the <application>Orca</application> community continually works to provide superior access to more and more applications.
</para>

<section>
<title>Using Adobe's Acrobat Reader</title>
<para>
We are currently working on a script for Adobe's Acrobat Reader, and the initial version has been contributed to <application>Orca</application> v2.17.5. Note that there is still work to do, and we are very encouraged by Adobe's commitment to accessibility.
</para>

<section>
<title>Installation</title>
<para>
If you get Adobe Acrobat Reader directly from the <ulink url='http://www.adobe.com/products/acrobat/readstep2.html'>Adobe site</ulink>, you may find that the software will not launch. If launched from the Applications menu, it may appear that nothing has happened, or if launched from a terminal window you may receive a long series of syntax error messages. Should this occur, you will need to edit your /usr/bin/acroread file as described in this <ulink url='http://ubuntuforums.org/showthread.php?t=233514'>Ubuntu forum thread</ulink>.
</para>
<para>
If you instead choose to install Acrobat Reader from your distribution's packages, be sure to install both <application>acroread</application> and <application>acroread-plugins</application>. Without the plugins package, you will not have the access to the "Reading" category in the <menuchoice>
<guimenuitem>Edit-</guimenuitem>
<guimenuitem>Preferences</guimenuitem>
</menuchoice> dialog.
</para>
<para>
Note: If you use Ubuntu and cannot locate the
<application>acroread</application> package, you will likely need to edit your /etc/apt/sources.list to include the 'multiverse' repository. Then run <userinput>apt-get update</userinput>. Having done so, you should then be able to install both <application>acroread</application> and <application>acroread-plugins</application>.
</para>
</section>

<section>
<title>Enabling Accessibility and Caret Navigation</title>
<para>
Once you've installed Reader, you need to enable accessibility:
</para>
<orderedlist numeration='arabic'>
<listitem>
<para>
In the "Accessibility" tab of the 
<menuchoice>
<guimenuitem>Edit-</guimenuitem>

</menuchoice> dialog, make sure 
<guilabel>Always display the keyboard selection cursor</guilabel> (<keycombo>
<keycap>Alt</keycap><keycap>D</keycap>
</keycombo>) is checked.

<guilabel>Enable Document Accessibility
</guilabel> ((<keycombo><keycap>Alt</keycap>
<keycap>E</keycap></keycombo>) is checked.
</para>
</listitem>
</orderedlist>
</section>

<section>
<title>Working with Untagged Documents</title>
<para>
When you open an untagged document, you will be presented with a dialog box asking you to specify the reading order and the reading mode options. The default reading order is 
<guilabel>Infer reading order from document
</guilabel>. This setting works well for most documents.
</para>
<para>
The default reading mode will vary depending on the length of the document; for short documents, the default is <guilabel>Read the entire document</guilabel>; for long documents the default is <guilabel>Read currently visible pages only</guilabel>. <application>Orca</application> tends to work better when <guilabel>Read the entire document</guilabel> is selected.
</para>
<para>
If you find that a document seems to be missing parts of the text, try changing the reading options. To do so, get into the Document menu and select <guilabel>Change Accessibility Reading Options...</guilabel> or use the shortcut <keycombo><keycap>Ctrl</keycap><keycap>Shift</keycap><keycap>5</keycap></keycombo>.
</para>
</section>

<section>
<title>Page Layout</title>
<para>
The best page layout for reading a document with <application>Orca</application> is <guilabel>Single Page</guilabel>. When <guilabel>Continuous</guilabel> is chosen, moving focus to text as the page is scrolling 
can cause that text not to be read. You can change the page layout to <guilabel>Single Page</guilabel> by getting into the View menu and selecting the Page Layout submenu.
</para>
</section>

<section>
<title>Navigating Tables</title>
<para>
As far as we know there isn't currently a whole lot of keyboard support for tables in
<application>Acrobat Reader</application>. We hope Adobe will remedy this soon.
</para>
<para>
Basically, there are the arrow keys. Their behavior is to move you first within the cell with focus, then to the next cell with data in it. Note that currently, Up and Down Arrow do not seem to move you vertically among cells - at least that has been the experience 
with the tables we have tried. Instead, Up and Down seem to move you horizontally until you run out of cells on the current row.
</para>
</section>
</section>

<section>
<title>Making Application-Specific Settings</title>
<para>
To customize the settings for a particular application, you will first need to run that application. Make sure the application has focus, then press <keycombo><keycap>Orca_Modifier</keycap>
<keycap>Ctrl</keycap><keycap>Space</keycap>
</keycombo> (by default, this will be 
<keycombo><keycap>Insert</keycap><keycap>Ctrl</keycap>
<keycap>Space</keycap></keycombo> for the Desktop keyboard layout).
</para>
<para>
This brings up a tabbed dialog window very similar to the <application>Orca</application> configuration dialog, but with the following differences:
</para>
<orderedlist numeration="arabic">
<listitem>
<para>
There is no initial General pane.
</para>

boxes on the Speech pane will be grayed out (made inactive).

</para>

There may be a new application-specific settings pane at the end of the set of tabbed panes. Note that pressing the End key from the tab list will get you directly to the right-most tab.
</para>
</listitem>
</orderedlist>
<para>
Adjust your application-specific settings in the same way you set your general <application>Orca</application> preferences.
For example, you may have Key Echo disabled generally in <application>Orca</application> but would like to specifically have it enabled for the <application>gcalctool</application> (GNOME Calculator) application. Here's where you could easily set that.
</para>
<para>
When you have your application settings customized the way you want, press the <guilabel>OK</guilabel> button. These settings will be written to your 
<userinput>~/.orca/app-settings</userinput> directory in a file called 
<userinput>&lt;APPNAME&gt;.py</userinput>, where <userinput>&lt;APPNAME&gt;</userinput> is the name of the application.
</para>
<para>
These files are automatically written by <application>Orca</application>. The contents of the file will be overwritten each time you change your application settings for that
application.
</para>
<para>
If you want to have some extra application-specific settings or code that you don't want to lose, then you should put it in a file called <userinput>~/.orca/app-settings/&lt;APPNAME&gt;-customizations.py</userinput>. This file will be automatically read when the settings for the 
<userinput>&lt;APPNAME&gt;</userinput> application are loaded.
</para>
<para>
Note that this is an advanced feature that we don't expect many people to use. It's just there if you really want it.

<para>
There is currently one known bug (some people would call it a feature) that we are trying to track down and fix:
</para>
<note>
<para>
If you adjust one or more application-specific key bindings, the new values will not take effect until you've pressed the <guilabel>OK</guilabel> button. The work-around is to either restart <application>Orca</application>, or Alt-Tab 
away to some other application and then Alt-Tab back to the one that you've just changed the key bindings for.

<title>Braille</title>
<para>
<application>Orca</application> uses 
<ulink url="http://mielke.cc/brltty/">BrlTTY</ulink> for braille support. On Linux systems, BrlTTY is used to access the text mode console content. On a typical braille-enabled installation of Linux, BrlTTY is already running and providing access to the text consoles. When Orca starts, it connects to BrlTTY. If you switch from a text console to your X Windows session, your braille display will automatically follow and display the content that Orca is presenting to you.
</para>
<para>
<application>Orca</application> attempts to work with various releases of BrlTTY. Orca currently works best with BrlTTY v3.8 or better and also works well with BrlTTY v3.7.2. The remainder of this document provides information related to using <application>Orca</application> with <application>BrlTTY</application> 3.8.
</para>

<para>
Below are descriptions of the necessary tasks to install/setup BrlTTY in Ubuntu and Solaris. For both, you need to first obtain 
<ulink url="http://mielke.cc/brltty/releases/ brltty-3.8.tar.gz">brltty-3.8.tar.gz</ulink> from the BrlTTY site.
</para>

<section>
<title>BrlTTY 3.8 on Ubuntu</title>
<para>
First, configure your build environment to build BrlTTY. Much of this setup is done for you automatically in the Ubuntu distribution with products such as G++ already present. In addition, <emphasis>you must</emphasis> 
also install tcl, Pyrex, and the Python developer environment. To do this, execute the following commands as <userinput>root</userinput>:
</para>
<para/>
<screen>
<![CDATA[apt-get build-dep brltty
apt-get install tcl8.4 python-pyrex python-dev
]]>
</screen>
<para>
Then, when you build BrlTTY, avoid configuring the package with --prefix=/usr. Use the standard procedure instead, executing the following commands as <userinput>root</userinput>:
</para>
<para/>
<screen>
<![CDATA[gunzip -c brltty-3.8.tar.gz | tar xvf -

If you want, you can remove the existing 
<userinput>/sbin/brltty</userinput> and replace it with the <userinput>/bin/brltty</userinput>, either by copying the <userinput>/bin/brltty</userinput> to <userinput>/sbin/brltty</userinput> or just by making a

Mobility impairments can be caused by arthritis, stroke, cerebral palsy, Parkinson's disease, multiple sclerosis, and loss of limbs or digits, among others. Poor muscle control or weakness can make using standard keyboards and mouse devices difficult.

setting is 0.4 seconds, you must perform the second click of a double-click within 0.4 seconds of the first click. If the second click occurs more than 0.4 seconds after the first click, the system interprets the two clicks as two single clicks. 
</para>

To configure the double-click timeout setting, perform the following steps:

Use the <guilabel>Timeout</guilabel> slider to specify the timeout in seconds that the system allows between the two clicks of a double-click. Moving the slider to the right will increase the timeout interval in 0.1 
second intervals. In the same manner, moving the slider to the left will decrease the timeout in 0.1 second intervals.
</para>

<para>
Double-click on the light bulb to the right of the slider to test the setting. If you perform the two clicks of the double-click within the timeout specified, the light bulb lights up fully to display a yellow glow around the bulb. If you do not double-click 
within the timeout specified, the light bulb does not light fully. You should increase the timeout setting and try again. When the light bulb lights, the timeout setting is suitable for your needs.

A toggle key is any key on the keyboard that
can switch between two states. The <keycap>Num Lock</keycap>, <keycap>Caps Lock</keycap>, and <keycap>Scroll Lock</keycap> keys are toggle keys. Most toggle keys have an associated light emitting diode (LED) on the keyboard that lights when the toggle key 
is active. To assist users with visual impairments, you can customize the keyboard to emit an audible notification when a user presses a toggle key. For example, when you press <keycap>Num Lock</keycap>, you can determine whether the key is toggled or not 
by the sound emitted.
