xyzzy /X-Y-Z-Z-Y/, /X-Y-ziz'ee/, /ziz'ee/, or /ik-ziz'ee/ adj.    [from the ADVENT game] The {canonical} `magic word'.   This comes    from {ADVENT}, 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!"   It's traditional for    xyzzy to be an {Easter egg} in games with text interfaces.          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".          Early versions of the popular `minesweeper' game under Microsoft    Windows has a cheat mode triggered by the command    `xyzzy' that turns the top-left pixel of the    screen different colors depending on whether or not the cursor is    over a bomb.   This feature seems to be gone in the 32-bit (Windows    98 and later) versions.       = Y =
