Keyboard and mouse Accessability

Both Microsoft Windows and the X Window System have features designed to aid users with disabilities. These features are StickyKeys, MouseKeys, SlowKeys, BounceKeys, RepeatKeys, and TimeOut.

In Microsoft Windows, these can be enabled by adjusting the Accessability Options from the control pannel.
When on a Sun console, these can be adjusted with the accessx graphical user interface. This supports all but MouseKeys.
When using the X server (XFree86) in Linux, the following features are available:

Accessability in XFree86 / Linux

StickyKeys

to enable, press the shift key 5 times.
to use, press and release each needed modifier key (shift, control, alt), and then press the desired key.
to disable, either press a modifier key together with a regular key, or press shift 5 times again.
If this does not work, it is possible the +accessx option was not given to the X server on the workstation.

MouseKeys

to enable (or disable) press Ctrl-Alt-Shift-Numlock (you can use stickykeys on this). (If the Numlock light changes, it didn't work.)
Alternately, run the following command:
```
   xmodmap -e "keysym Num_Lock = Num_Lock Pointer_EnableKeys" 
```
And then type shift numlock to enable mousekeys.

Use the following sequences on the KEYPAD to emulate the mouse:

mouse buttons
5	press default mouse button
0	pres/lock default mouse button
.	release/unlock default mouse button
+	double click default mouse button
change default mouse button
/	set default button to Button1
*	set default button to Button2
-	set default button to Button3
Arrow mouse buttons
1	down left
2	down
3	down right
4	left
6	right
7	left up
8	up
9	right up

SlowKeys, BounceKeys, RepeatKeys, and TimeOut

These are supported, but no documentation was found on how to enable them. If you wish to use any of these, please ask me and I will research them.
