Computer programmers historically used "Press any key to continue" (or a
similar text) as a prompt to the user when it was necessary to pause
processing. The system would resume after the user pressed any

History "Press any key to continue."
Early computers were typically operated using mechanical teleprinters,
which provided a continuous printed record of their output. However, during the
1970s, these became obsolete and were replaced with visual display units (see
computer terminal), and text was lost once it scrolled off the top of the screen. To
compensate, programs typically paused operation after displaying one screen of
data, so that the user could observe the results and then press a key to move to
the next screen.
A similar pause was also required when some hardware action was required from
the user, such as inserting a floppy disk or loading a printer with paper.
These prompts were commonplace on text-based operating systems prior to the

enable the user to view more than one screen/window of data. They are therefore
no longer required as a means of paginating output, but the graphical equivalent
(such as "Click OK to continue") is still used for hardware interactions.
The prompt is not strictly accurate in that, for the vast majority of computer systems, modifier keys or lock keys would not
cause processing to resume, as they do not produce an actual character that the program could detect.
Some Samsung remote controls for DVD players, as is the case of DVD-R130, have included an "anykey" to their interface. It
is used to view the status of the DVD being watched. 
There are reports that some users have searched for such a key labelled "any", and called technical support when they have
been unable to find it.  The computer company Compaq  even edited their FAQ to explain that the "any" key does not
exist,  and at one point considered replacing the command "Press any key" with "Press return key". 
The concept of the "any key" has become a popular piece of computer-related humor,  in part because of an episode of
The Simpsons in which main character Homer Simpson asks "Where's the any key?" when confronted with the "press any
key" command. Plastic "any keys" with adhesive backings are available as novelty gifts.
