A thought occured to me as I was trying to figure out setting up X-Windows to use certain editing shortcuts: ^Z = Undo ^X = Cut ^C = Copy ^V = Paste ;how the ^H^H^H^H does a v represent insert text from cut buffer? These are ubiquitous now in Windows programs, but who came up with this group of editing shortcuts that cluster so neatly on the bottom left of the keyboard, right by the Ctrl key back in the early micros?
