# Configuring the Mouse and Keyboard

This chapter describes how to configure the mouse and keyboard to make these devices accessible to more users.

## Configuring the Mouse

Use the Mouse preference tool to configure the mouse to suit your needs. To open the Mouse preference tool, choose Applications Desktop Preferences Mouse. The Mouse Preferences dialog is displayed.

### To Configure the Behavior of the Mouse

The following sections describe how to modify the behavior of the mouse to suit your needs.

#### To Configure the Mouse for Left-Handed Use

To configure the mouse for left-handed use, click on the Buttons tab in the Mouse Preferences dialog, then select the Left-handed mouse option. When you select this option, the system swaps the functions of the left mouse button and the right mouse button immediately.

#### To Configure the Double-Click Behavior

If you have difficulty double-clicking, you can increase the period of time that the system allows to elapse between the first click and the second click of a double-click. For example, if the double-click timeout 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.

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

1. Click on the Buttons tab in the Mouse Preferences dialog.

2. Use the Delay slider to specify the timeout in seconds that the system allows between the two clicks of a double-click.

3. 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.

#### To Configure the Speed and Sensitivity of the Mouse

To configure the speed and sensitivity of the mouse, perform the following steps:

1. Click on the Motion tab in the Mouse Preferences dialog.

2. Configure the following options:

   Acceleration

     Use the slider to specify the speed at which the mouse pointer moves around the screen when you move your mouse.

     If you select a low setting, the mouse pointer moves at a speed similar to the speed at which you are physically moving the mouse. This means that you need to physically move the mouse larger distances to cover the screen area. If you select a high setting, the mouse pointer moves at a faster speed than the speed at which you are physically moving the mouse. This means that you need to physically move the mouse small distances to cover the screen area.

   Sensitivity

     Use the slider to specify how sensitive the mouse pointer is to movements of your mouse.

   Threshold

     Use the slider to specify the distance that you must move an item before the system interprets the move action as a drag-and-drop action.

#### To Locate the Mouse Pointer

If you have difficulty locating the mouse pointer on the screen, you can enable an option to highlight the pointer when you press the Control key. To enable this option, click on the Cursors tab in the Mouse Preferences dialog, then select the Show position of cursor when the Control key is pressed option. When you press Control, the system displays an animation around the pointer to highlight the pointer.

On some platforms, you must log out and log in again before this setting takes effect.

### To Configure the Mouse Pointer

The following sections describe how to modify the display characteristics of the pointer.

#### To Change the Pointer

To select the type of pointer that is displayed on the desktop, perform the following steps:

1. Click on the Cursors tab in the Mouse Preferences dialog.

2. Select one of the following themes from the pointer themes that are listed in the Cursor Theme list box:

   - Default Cursor

     Displays the default black pointer.

   - White Cursor

     Displays a white pointer that is the same size as the default pointer.

   - Large Cursor

     Displays a large black pointer.

   - Large White Cursor

     Displays a large white pointer.

3. To change the pointer theme, you must log out of your session and log in again.

#### To Stop the Cursor Blinking

To stop the cursor blinking in text boxes and fields, perform the following steps:

1. Choose Applications Desktop Preferences Keyboard to start the Keyboard preference tool.

2. In the Keyboard tabbed section, deselect the Blinks in text boxes and fields option.

### To Use the Keyboard to Emulate the Mouse

If you have difficulty using a mouse, you can use the keyboard to emulate the mouse functions. See of this manual for more information.

## Configuring the Keyboard

Use the Keyboard Accessibility preference tool, also known as AccessX, to configure the keyboard accessibility options. To start AccessX, choose .Applications Desktop PreferencesAccessibility Keyboard.

The AccessX dialog enables you to customize your keyboard in the following ways:

- To use the numeric keypad to emulate mouse actions. See .

- To specify the duration for which you must press-and-hold a key before the system accepts the keypress. See .

- To ignore rapid, repeated keypresses of the same key. See .

- To accept key combinations in sequence rather than simultaneously. See .

- To emit an audible notification when a user activates or deactivates a toggle key. See .

- To ignore long keypresses of the same key and control the repeat rate of a keypress. See .

### Before You Can Use AccessX in the Solaris™ Operating Environment

If you are using the GNOME desktop for the Solaris™ 8 operating environment or the Solaris 9 operating environment, you must enable XKB on your system before you can use the AccessX preference tool.

XKB is not currently supported on Sun Ray™ systems.

To enable XKB on a non-Sun Ray Solaris system, perform the following steps:

1. Log in as root.

2. Check if the path and file `/etc/dt/config/Xservers` exists on your system.

3. If the `/etc/dt/config` directory does not exist, enter the following command:

                   mkdir -p /etc/dt/config

4. If the `Xservers` file is not present, enter the following command:

                   cp /usr/dt/config/Xservers /etc/dt/config/Xservers

5. Open the `Xservers` file in a text editor and scroll to the end of the file.

6. Append the following to the command line at the end of the file:

                   +kb

7. Save and close the file.

8. Enter the following command at a command line:

                   pkill -HUP dtlogin

9. Log out of your GNOME session and log in again.

10. To verify if XKB is running, enter `xdpyinfo` and search for XKEYBOARD in the extensions list.

### To Activate the Keyboard Accessibility Options

To activate the keyboard accessibility options, perform the following steps:

1. Select the Enable keyboard accessibility features option.

2. Click on the Basic tab to display the Basic tabbed section.

3. Select the Beep when features turned on or off from the keyboard option to receive an audible notification each time a user enables or disables a keyboard accessibility option using the following keyboard shortcuts:

   - Press-and-hold Shift for eight seconds to enable or disable the slow keys feature.

   - Press Shift five times to enable or disable the sticky keys feature.

4. To automatically disable the keyboard accessibility options if the options are not used for a specified number of seconds, select the Disable if unused for X seconds option. Use the slider to specify the number of seconds of keyboard idle time required before the system disables the keyboard accessibility options.

   This option is intended for computers that are shared by a number of different users, some of whom require the keyboard accessibility options.

5. If you are a GNOME for Linux user, you must log out and log in again before the accessibility settings take effect.

### To Enable the Keyboard to Emulate the Mouse

The mouse keys feature enables you to use the numeric keypad on the keyboard to emulate mouse actions. This feature benefits users who have difficulty using a mouse or other pointing device. To enable and configure the mouse keys feature, perform the following steps:

1. Click on the Mouse tab to display the Mouse tabbed section.

2. Select the Enable Mouse Keys option.

3. Configure the following options to determine the behavior of the mouse pointer when you control the pointer from the numeric keypad:

   Maximum pointer speed

     Use this spin box to specify the maximum speed, in pixels per second, at which the pointer moves around the screen.

   Time to accelerate to maximum speed

     Use this spin box to specify the duration, in milliseconds, before the pointer accelerates to the maximum pointer speed.

   Delay between keypress and pointer movement

     Use this spin box to specify the interval, in milliseconds, between a keypress and the time when the pointer starts to move.

When you enable mouse keys, the keys on the numeric keypad have the following functions:

### To Enable the Slow Keys Feature

The slow keys feature enables you to customize how the keyboard handles user input in the following ways:

- Specify the duration for which you must press-and-hold a key before the system accepts the keypress. This aspect of the feature benefits users who frequently press keys that they do not intend to press.

- Enable audible indications of keyboard input and acceptance. This aspect of the feature benefits users who cannot see the result of a keypress.

To enable and configure the slow keys feature, perform the following steps:

1. Click on the Filters tab to display the Filters tabbed section.

2. Select the Enable Slow Keys option.

   To select or deselect this feature from the keyboard, press-and-hold Shift for eight seconds. This keyboard shortcut automatically selects all of the slow keys options. If you selected the Beep when enabling/disabling keyboard accessibility features option, after four seconds the system beeps three times to indicate that the system is about to select or deselect the feature. If you enable this feature from the keyboard, you must press-and-hold Shift for eight seconds again to disable the feature.

3. Use the Only accept keys held for slider or spin box to specify the duration, in milliseconds, for which you must press-and-hold a key before the system accepts the keypress. Use the Type to test settings text box to test the slow keys setting and modify the setting as required.

4. To enable audible indications of keyboard input and acceptance, select the following options:

   Beep when key is pressed

     Select this option to hear a beep when you press a key.

   Beep when key is accepted

     Select this option to hear a beep when the system accepts a keypress.

   Beep when key is rejected

     Select this option to hear a beep when the system rejects a keypress. The system rejects a keypress if you do not press-and-hold the key for the duration that is specified in the Only accept keypress after x msecs setting.

### To Enable the Bounce Keys Feature

The bounce keys feature enables you to customize the keyboard to ignore rapid, repeated keypresses of the same key. For example, users with impaired motor skills might press the same key several times when they intend to press the key once. This feature enables you to customize the keyboard to ignore repeated keypresses.

To enable and configure the bounce keys feature, perform the following steps:

1. Click on the Filters tab to display the Filters tabbed section.

2. Select the Enable Bounce Keys option.

3. Use the Ignore duplicate keypresses within slider or spin box to specify the duration after the first keypress for which the system ignores repeated keypresses of the same key. For example, if you select a duration of 500 msecs, the system ignores all repeated keypresses of the same key that occur within 500 msecs of the first keypress.

4. Select the Beep if key is rejected option to hear an audible indication when the system ignores a key.

If you wish to enable the bounce keys feature, please ensure that the Enable Slow Keys option is deselected. The slow keys feature requires you to press a key for a specified duration before the system accepts the keypress as a valid keypress. If you cannot press the key for the duration that is specified by the slow keys setting, the system does not accept your input unless you deselect the Enable Slow Keys option.

### To Enable the Sticky Keys Feature

The sticky keys feature enables you to press the keys in a key combination in sequence rather than simultaneously. This feature is designed for users who are unable to press two or more keys simultaneously.

To enable and configure the sticky keys feature, perform the following steps:

1. Click on the Basic tab to display the Basic tabbed section.

2. Select the Enable Sticky Keys option.

   To enable the sticky keys feature from the keyboard, press Shift five times. This keyboard shortcut automatically selects all of the sticky keys options. If you selected the Beep when enabling/disabling keyboard accessibility features option, the system beeps to indicate that the system is about to select or deselect the feature. If you enable this feature from the keyboard, press Shift five times again to disable the feature.

3. Select the Beep when modifier is pressed option to receive an audible indication each time you press a modifier key. This option is useful to remind you whether a modifier key is active or inactive.

4. To automatically disable the sticky keys feature when a user presses two keys simultaneously, select the Disable if two keys pressed together option.

You can use the sticky keys feature in latch or lock mode. The following table describes how to choose a mode and the difference between the two modes.

#### Sticky Keys Latch or Lock Mode

To use the sticky keys feature in... | Press the modifier key... | The modifier key stays active until...
--- | --- | ---
Latch mode | Once. | You press a non-modifier key.
Lock mode | Twice in quick succession. | You press the modifier key again.

For example, if you want to press AltF1, you should do the following:

1. Press Alt to latch the modifier key. The Alt key remains active.

2. Press F1. The key combination is now complete. After you press F1, the Alt modifier key is no longer active.

As another example, if you want to press CtrlAltTab, you should do the following.

1. Press Ctrl twice to lock the modifier key. The Ctrl remains active.

2. Press Alt.

3. Press Tab. The key combination is now complete.

4. To unlock the modifier key, press Ctrl again.

### To Enable Audible Notifications for Toggle Keys

A toggle key is any key on the keyboard that can switch between two states. The Num Lock, Caps Lock, and Scroll Lock 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 Num Lock, you can determine whether the key is toggled or not toggled by the sound.

To enable accessible toggle keys, select the Enable Toggle Keys option in the Filters tabbed section. When you activate the Num Lock, Caps Lock, or Scroll Lock keys, the system beeps once. When you deactivate a toggle key, the system beeps twice.

### To Enable the Repeat Keys Feature

The repeat keys feature enables you to repeat a keystroke multiple times without pressing the key more than once. This feature is designed for users who cannot release keys quickly, for example users who operate a mouth stick. When you enable repeat keys, you can specify the duration for which you must press a key before the key starts to repeat.

To enable and configure the repeat keys feature, perform the following steps:

1. Click on the Basic tab to display the Basic tabbed section.

2. Select the Repeat Keys option to enable the repeat keys feature.

3. Use the Delay slider to specify the duration for which you must press a key before the keyboard interprets the action as a repeat key. If you have difficulty releasing keys, select a long time delay.

4. Use the Speed slider to specify the speed at which the keyboard repeats the keypress as input.
