Mapping keyboard key position onto the screen should also be an option
for a pointing device:  

	1) some key combination to toggle between usual keyboard
	input and pointing input; 
	2) duration of pressing keys as indication of 
	zero order input (as in touch screen -- mapping key location 
	onto screen) or first order input (as in trackball -- 
	moving cursor relatively)

Hey this may be done softwarely and any late night programmers hear this?
