how to make a arrow only keyboard?

im converting a laptop to a tablet pc but i want to be able to duel boot it with linux jolicloud because it looks like it should be a tablet os, and windows because of the things available for it.
to do this i will need the arrow keys and the enter key but i dont want to have a whole keyboard just for those 5 keys.
ive been looking around for the answer for a couple of weeks now and ive found out how keyboards work but not how to make one with arrows and the enter keys.
thanks

You could use/make a small microcontroller that uses standard momentary buttons as keys.

You can get seperate "number pad" keyboards. That may do the job for you.
