Does anyone know where to find programmable pads ?!!

I'd like to be able to do all the
CTRL+W
CTRL+E
CTRL+X
CTRL+C
CTRL+V
CTRL+Z
CTRL+S
etc ...
with one button at time !!!

I've been editing a cd-rom with 3000 sound files.
Using "small-finger" on CTRL-button all the time is killing
all of my left hand ..

Help !!!

yours mika
