Ah, but I've become a fanatic about keyboard shortcuts as of late. I bought this Logitech USB gaming keyboard with 18 programmable keys, over 3 selector switches for a total of 48, that can be mapped to pretty much anything, even to open programs. I'm getting lazy in my old age. ;)
Plus, I've gotten so used to using shortcut keys with LW, it's become second nature.

I would think it would be possible to map keys to any unique body part names and store that info in the relevant cr2 file, no?
