More things to ~steal~ take inspiration from, thank you :). If I'm completely naive with my approach, I would have 5 fingers * 4 directions * 2 hands. That's a paltry 40 keys. To make matters worse, some of them are sub-optimal: the ring finger isn't great at sideways movements (at least on my hand). 35-40 keys is end-game enthusiast level minimalism.
