The KDE Control Center offers several keyboard features collectively called XAccess. They include:
- Sticky Keys
This feature permits operation of meta keys, such as Alt, Ctrl, and Shift without having to hold the keys down. It is useful when you can only use one finger or one hand to operate the keyboard. With Sticky Keys on, press and release a Alt, Ctrl, or Shift key, then press another key. The result is as if you pressed both keys at once. Press the Alt, Ctrl, or Shift key again to turn off the sticky key. Activate this feature in → → → → .
- Slow Keys
This feature is useful if you have hand tremors or difficulty accurately pressing keys. It prevents inadvertent key presses by requiring that a key be held down for a minimum time before it is accepted. Act ivate this feature in → → → → .
- Bounce Keys
This feature is also useful if you have hand tremors. It prevents inadvertent repeated key presses by preventing another keystroke for a certain amount of time. Activate this feature in → → → → .
Mouse Emulation permits you to move and click the mouse using the keyboard. Press Alt+F12 to activate it. Use the arrow keys to move the mouse pointer to the desired location, and press spacebar to "click" the mouse. Unfortunately, you cannot use Mouse Emulation to perform mouse button clicks or dragging.
This feature permits you to emulate the mouse using the numeric keypad of your keyboard. To activate it, go to → → → → . Check the Move pointer with keyboard (using the num pad) box. When you do this, the other settings will become enabled, and you can customize the keyboard pointer behavior further, if required. The various keys on the number pad move in the direction you would expect. Note that you can move diagonally as well as up, down, left and right. The 5 key emulates a click to a pointer button, typically mouse button. You change which button is emulated by using the / key (which makes it mouse button), * key (which makes it middle mouse button) and - (which makes it mouse button). Using the + emulates a doubleclick to the selected pointer button. You can use the 0 key to emulate holding down the selected pointer button (for easy dragging), and then use the . to emulate releasing the selected pointer button.
