Hmmmmmmm, for super touch-type know-all-the-shortcut-keys people probably the best thing would be a very light-weight headset with laser tracking.  On rare occasions when you want to use the mouse, the tracking would move the mouse pointer to the point you are looking at.  You could wiggle your ears or blnk hard to double-click.

With the electronics so cheap nowadays there may even be something out there.  I know combat pilots have had this laser eye-sight tracking stuff for quite awhile.

This kind of stuff already exists for the disabled, but it is really expensive.

There is foot controlled input devices, too, and they seem to be much cheaper:

I actually worked at a company that had one of those foot-activated mice. It was... weird. Hard to get used to. But certainly very novel.

It should type ATCHOO!

I want an ANY KEY!

I suppose taking away the useless Scroll Lock key and Windows menu key?

The Scroll Lock key is not useless for those of us who play Joint Operations, (or any of the Novalogic games).  Toggling it is the equivalent of holding down the forward motion key, (known as AutoRun ), and it's function can't be remapped, (although I suppose the useless CapsLock could be remapped to Scroll Lock - dammit, why didn't I think of that before!  Then I wouldn't have had to reach across the keyboard to use it...).
