The laptop doesn't fit on my desk.  I got the docking station to be able to use the laptop at home.

Can anyone recommend a way to switch a keyboard and a trackball between (at least) two 
computers without the keyboard forgetting the key repeat rate and delay when switching and 
with a trackball using an USB dongle rather than a cable?  (It's the only left handed trackball I 
could find in the last 25 years, otherwise I wouldn't have a wireless one.)  The keyboard is also 
USB.  I wouldn't want to spend a fortune on such a switch, and it would have to be small enough 
to fit on my desk.
