Vulcan nerve pinch
n.
[from the old Star Trek TV series via Commodore Amiga hackers] The
keyboard combination that forces a soft-boot or jump to ROM monitor
(on machines that support such a feature). On Amigas this is
<Ctrl>-<Left-Amiga>-<Right-Amiga>; on PC clones this is Ctrl-Alt-Del;
on Suns, L1-A; on Macintoshes, it is <Cmd>-<Power switch> or
<Cmd>-<Ctrl>-<Power>! On IRIX,
<Left-Ctrl><Left-Shift><F12><Keypad-Slash>, which kills and restarts
the X server, is sometimes called a vulcan nerve pinch. Also called
{three-finger salute} and Vulcan death grip. At shops with a lot of
Microsoft Windows machines, this is often called the Microsoft
Maneuver because of the distressing frequency with which Microsoft's
unreliable software requires it. Compare {quadruple bucky}.
