Since the window menu actions that aren’t terrible with keyboard also have their own direct keyboard shortcuts (move and size are the ones that don’t, but hand positioning windows instead of using snap positions is tedious with keyboard), I wouldn’t be surprised if that’s a fairly rare thing.

I was thinking about Maximise, Restore, and Minimise, which I think were Alt+Space {X,R?,N} (haven’t used Windows for a few years), but I suppose Win+Up is now Maximise, and Win+Down Restore and Minimise—but you still need Alt+Space N to minimise from maximised.
