xkbset is a program rather like xset in that it allows you to set various
features of the X window interface. It allows one to configure most of the
options connected with the XKB extensions. They are described in Section 10 of
XKBlib.ps.
This includes customizing the following:
MouseKeys: using the numeric pad keys to move the mouse;
StickyKeys: where modifiers like control and shift will lock until the
next key press (good for one finger typing);
SlowKeys: The keys will not work unless they are pressed for a certain
amount of time;
BounceKeys: If a key is pressed more than once rapidly, only one key
press will be registered.
