Yeah I find that this style of cheat sheet where it's overlayed on a keyboard aren't really that useful when you know what feature you want, but don't know the key.
They make more sense for reverse-engineering, i.e. you accidently just hit a key, and you want to find out what it did.
I guess they still are useful to study in one big go, when you have some time to sit down and purely just study + practise keybindings (not working on real code) and helps with muscle memory kind of thing.
But less so when I'm being impatient and just want to figure out one thing that I need right now (while working on some real project).
