Three Finger Salute

The keyboard combination that, under DOS, forces a warm (or soft) re-boot. On the great majority of PCs this is Ctrl+Alt+Delete but other machines may use other combinations. With Windows® 95 and beyond, Microsoft intercepted this command and presented some user options. However, if the PC is really hung, then continued three fingered salutes would normally cause a reboot. (Alternatively, most of us powered off or 're-set', at this stage). This was a favourite part of the PC user's day in the early 1990s when Microsoft Windows® 3.1 / 3.11 used to crash, freeze, and generally stop working, on a regular basis.
