"[...] Ctrl+Alt+Del because it was impossible to press with just one hand." At first I thought, "Well, not impossible, really...", because you can "play the chord" with your right hand: Pointer (Ctrl) + Thumb (Alt) + Middle (Delete) But... The older keyboards [1] only had a single "Ctrl" key and a single "Alt" key. They were located on the left side of the keyboard, while the single "Del" key was located on the right side. So, with that configuration, it actually was impossible to perform the combination with a single hand.
