When using computers, I often want to send more inputs than my keyboard can. I once tried to use a foot pedal (a.k.a. footswitch) to send mouse clicks and modifier keys, but it seemed to put a lot of strain on my ankle. Is it possible to use a foot pedal to send mouse clicks and modifier keys without getting any RSI-like issues, and if so, how shall I use it ergonomically?
