Three-finger salute
In computing, the three-finger salute is a jocular term for the keyboard combination that forces a soft boot or jump to ROM monitor (on machines that support such a feature). It is also known as the "Vulcan nerve pinch" or "Vulcan death grip" from the original Star Trek TV series.
