The keyboard is mostly not used, just a few keys, the mouse gets full of crap and needs space to work.
I thought of a touch-screen monitor but then i lose the jog arrow keys which are far better than the tab fly-out screen in Mach.
I then thought of a keyboard track-pad but these are pretty expensive.
Next up was a keyboard track-ball - this is possibly what i'll get but is there a better method????
I can't fit a pendant as the serial port is used by my THC, so i need an easy method to jog the torch around.
Any ideas
