< games > The canonical "magic word" from the ADVENT adventure game, in which the idea is to explore an underground cave with many rooms and to collect the treasures you find there. If you type "xyzzy" at the appropriate time, you can move instantly between two otherwise distant points. If, therefore, you encounter some bit of magic , you might remark on this quite succinctly by saying simply "Xyzzy!" "Ordinarily you can't look at someone else's screen if he has protected it, but if you type quadruple-bucky-clear the system will let you do it anyway." "Xyzzy!" Xyzzy has actually been implemented as an undocumented no-op command on several OSes; in Data General's AOS/VS, for example, it would typically respond "Nothing happens", just as ADVENT did if the magic was invoked at the wrong spot or before a player had performed the action that enabled the word. In more recent 32 bit versions, by the way, AOS/VS responds "Twice as much happens". See also plugh .
