Accessibility options can be enabled by selecting Accessibility. This will open a new dialog, Keyboard Accessibility Preferences, also known as AccessX.
Before you can use the Keyboard Accessibility preference tool on Solaris systems, you must follow the steps outlined in Section A.3 ― Enabling XKB on Solaris Systems of this guide.
The Keyboard Accessibility Preferences (AccessX) dialog enables you to customize your keyboard in the following ways:
To activate the keyboard accessibility options, perform the following steps:
Choose System ▸ Preferences ▸ Keyboard and select Accessibility
Select the Enable keyboard accessibility features option.

This option is intended for computers that are shared by a number of different users, some of whom require the keyboard accessibility options.
Changes made will be instantly applied.
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:
In the Keyboard Accessibility Preferences (AccessX) dialog, select the Mouse Keys tab.
Select the Enable Mouse Keys option.
Configure the following options to determine the behavior of the mouse pointer when you control the pointer from the numeric keypad:
Use this spin box to specify the maximum speed, in pixels per second, at which the pointer moves around the screen.
Use this spin box to specify the duration, in milliseconds, before the pointer accelerates to the maximum pointer speed.
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:
| Numeric Keypad Keys | Function |
|---|---|
| 1, 2, 3, 4, 6, 7, 8, 9 | Move the mouse pointer around the screen |
| 5 | Mouse button click |
| 0 | Mouse button toggle |
| / | Primary mouse button |
| * | Secondary mouse button |
| - | Tertiary mouse button |
The toggle mouse button key enable the currently selected mouse button until the Mouse button click key is pressed. This allows you to perform drag and drop operations.
The Mouse button click emulates the currently selected mouse button. Pressing /, * or - will change the behaviour of this. The currently selected mouse button can be seen in the Keyboard Accessibility Status panel application, discussed in Section 2.3 ― Using the Keyboard Accessibility Status Panel Application.
The Primary mouse button is the left mouse button for right handed people. The Secondary mouse button is the right mouse button and the Tertiary mouse button is the middle mouse button.
Some Solaris systems also use the function keys to emulate the mouse buttons. The common function key to mouse button mappings are described in the following table.
The slow keys feature enables you to customize how the keyboard handles user input in the following ways:
To enable and configure the slow keys feature, perform the following steps:

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:
If you want to enable the bounce keys feature, 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, deselect the Enable Slow Keys option to enable the system to accept your input.

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 that the keyboard emits.
