I've got TMK on my Ergodox and I've got one key that's a layer modifier, and I'm wondering if I could offload that keypress (or hold) to a pedal for my foot. If I solder a wire to both sides of the keyswitch hole in the pcb, run that pair of wires out of the keyboard and to the ground where I can fashion a pedal out of scrap wood and something conductive, like aluminum foil maybe, then that should work right?
The keyswitch and the pedal would be in parallel so either would work, though they'd both have the same function.
It's not like I'm saving my self any effort, but it might be nice to have 2 full hands for 2nd layer keyboard work with neither having to hold anything down. Also it'd make me feel like a keyboard hotshot and that's pretty important!
I'll maybe mess around with the idea over break and let y'all know how it turns out. If anyone has any applicable experience or feedback, please share.
