xyzzy
/X.Y.Z.Z.Y/, /X.Y.ziz'ee/, /ziz'ee/, /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 had a cheat mode triggered by the command
`xyzzy<enter><right-shift>' that turns the top-left pixel of the
screen different colors depending on whether or not the cursor is over
a bomb. This feature temporarily disappeared in Windows 98, but
reappeared in Windows 2000.
The following passage from The Wonderful Wizard of Oz by L. Frank
Baum, suggesting a possible pre-ADVENT origin, has recently come to
light: "Ziz-zy, zuz-zy, zik!" said Dorothy, who was now standing on
both feet. This ended the saying of the charm, and they heard a great
chattering and flapping of wings, as the band of Winged Monkeys flew
up to them.
