Package xkbset

Tool to configure XKB extensions

http://www.math.missouri.edu/~stephen/software/#xkbset

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.
