Thought how great, for a split-second. But key for being 24/7 in front my computer with zero issues for decades is among other things—I move all the time, hence I need a keyboard which moves all the way with me and you can imagine that my feet are also moving their location and nobody wants to arrange all the foot paddles every time you move. And in these times in your home office it's great to put your feet up here and then.

Combine the camera for a facial expression based input instead? Grimace to change modes?

IDK I am totally fine with i, I and A haha and the brain is also faster when processing chords from the fingers only. If you blend feet or even just thumb strokes in you significantly slow down.

edit: just thinking of piano players, maybe I am wrong but this thing feels odd

maybe eyes blinking? Left eye blink -> i, again,<esc>, right eye -> (maybe) o , again <esc>

double blinking would be also fun to map!
