Hmmm, the Vulcan nerve pinch, the three finger salute, the Hail Mary keyboard combo, the three panic buttons. Ctrl-Alt-Del was a mistake because of buggy and sloppy code that caused the OS to crash. The person writing DOS had added it, I was told, because there was no reset button on the IBM PC 5150 system. IBM refused to install one, (later on PC Cloners added a Reset button along with a Turbo button to change the CPU clock speed) and so the programmer found three keys that most likely would not be accidentally pressed together by mistake and had to be pressed on purpose for the reset code to use. Control and Alt were next to each other, but Delete was way over on the other side of the keyboard. IIRC the Apple II had this issue and had used the Open Apple and Closed Apple with a "Reset" button, and because people would accidentally press the "Reset" button they had a change so that you had to hold down the Apple keys with the Reset key to reset the Apple II series. Later on Commodore made the Amiga and had the Amiga logo keys for resetting the Amiga series in AmigaDOS/AmigaOS.
