I tried it but this double duty doesn’t work for me. I’m pretty sure I also tried the Caps Lock as Esc but also as Ctrl. Well the main problem was just using the pinky on it so much. I’d rather do a left-up smack on the Esc key with the ring finger.

The crux of the matter is that I want to change my minds and/or not have to think about pressing a key and then bailing out. If it’s just a modifier key then no problem. What’s annoying is the specification “Windows-key”, and Windows OS-ification of it; that the single-key press causes an overwrought compositor animation where you get some gallery of the open applications. That’s even worse.
