Oh man, that’s a setup for the hall of fame! Awesome!
I believe you without a doubt when you say there’s no need for memorizing the keys! Muscle memory takes over when we have one key doing one job. On the contrary, with a mouse and a screen choke-full of control elements, our cursor can be anywhere at any given time, requiring that we take different paths to the same function, so muscle memory doesn’t come into play.
Bravo! I truly admire your setup!
