Three-finger salute (computing) Guide, Meaning , Facts, Information and Description
In computing, the three-finger salute is a jocular term for the keyboard combination that forces a soft boot, brings up the process manager (on Windows, BeOS or Mac OS X) or a jump to ROM monitor. These keys are sometimes referred to in computer manuals as interrupt keys, since they are often used to interrupt the operation of a malfunctioning program. The "three-finger salute" is named after the one-finger salute, a euphemistic name for a rude hand gesture. Other humorous synonyms include the "Vulcan nerve pinch" or "Vulcan death grip" from the original TV series.
