Keyboard Accessibility


These settings are designed to enable physically impaired users to use
a traditional keyboard. You can configure the following:



1) StickyKeys Allows users to lock modifier keys such as ctrl and
   shift. This enables them to complete keyboard tasks with just one
   finger that would normally require two or more fingers.


2) MouseKeys Enables key sequences to be used to move the mouse cursor
   on the screen and to send mouse clicks.


3) SlowKeys Configures the keyboard such that the user must hold a key
   down for a specified period of time before the keystroke is actually
   sent. This helps the user avoid sending accidental keystrokes.


4) ToggleKeys Sounds an audible alert if either the caps lock key or
   the num lock key is on.

5) RepeatKeys Configures the keyboard to allow the user extra time to
   release a pressed key before sending multiple keystrokes.


6) BounceKeys and DelayKeys Inserts a slight delay between keystrokes
   to prevent the keyboard from sending unintentional keystrokes.




To configure AccessX settings, access Universal Access and select the
option to configure keyboard preferences. For example, on a Fedora
system, you would select Typing Assist (AccessX) under Typing.
