Re: Keyboard commands for select, copy, paste and find
My favourite is when a (Windows) program opens a window in the wrong place, so that it is (or at least its title bar) is off-screen. There are times I think I'm the only person who knows about Alt-Space M to move a window using the keyboard. Surprisingly Alt-Space is fundamental enough it even works for TIFKAM (though M is Maximize there, since there is no Move).
I even remember baffling people when the last remaining computer in a lab at university had a broken mouse, but was running Windows. I'd not even sat down at it when someone told me not to bother, I told them I didn't need it and got on with what I needed to do via the keyboard.
