Well originally I intended to bind the left spacebar to space and the right spacebar to escape for when I’m using Helix editor (similar keybindings to Vim) to make escape faster to press. But I’ve found having the escape key in the first column second row beside my pinky to be very comfortable, so right now I have both of the keys set to space. But I am still editing what keys are where so this may well change.
I’m glad you like the keycaps by the way, I’m very happy with how they turned out.
