[[Image:DOS pause.png|thumb|The [[List of DOS commands#PAUSE|<code>pause</code> command]] in DOS requests the user to "Press any key to continue."]]

In computing, "Press '''any key''' to continue" (or a similar text) was a historically used prompt to the user when it was necessary to pause processing. The system would resume after the user pressed any [[Keyboard (computing)|keyboard]] button.

==History==
{{more citations needed|section|date=October 2018}}
Early computers were typically operated using mechanical [[teleprinter]]s, which provided a continuous printed record of their output. However, during the 1970s, these became obsolete and were replaced with [[computer terminal|visual display units]], 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 physical action was required from the user, such as inserting a [[floppy disk]] or loading a [[printer (computing)|printer]] with paper.

These prompts were commonplace on text-based [[operating system]]s prior to the development of [[graphical user interface]]s, which typically included [[scrollbar]]s to 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 a [[modal dialog]] box containing the text "Click OK to continue") is still used for hardware interactions.

The prompt ("''any'' key") is not strictly accurate, in that one is required to press a key which generates some sort of character. For the vast majority of computer systems, pressing [[modifier key]]s or [[lock key]]s 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.<ref>[http://downloadcenter.samsung.com/content/EM/200602/20060209163759000/EN/main.html DVD-R130<!-- Bot generated title -->]</ref>

{{quote|Do not tell the user to "press any key." ... On the Apple II series computers, you cannot read every key by itself: RESET, SHIFT, CONTROL. We have also found in testing that new users, in particular, panic when asked to press any key. Over 80% of them will turn around and say, "but what key should I press?" In questioning them about this response, we discovered that they are quite convinced that even though the prompt implied that all keys were OK to press, some could be dangerous. Of course, they were quite right.}}

There are reports from as early as 1988 that some users have searched for such a key labelled "any", and called technical support when they have been unable to find it.<ref name="cgw198811">{{cite magazine | title=Fantastic Voyages II / The Whirlwind Tour inside the Entertainment Industry Continues | magazine=Computer Gaming World | date=November 1988 | pages=42}}</ref><ref>{{cite news|author=Jared Sandberg|title='It Says Press Any Key; Where's the Any Key?'; India's Call-Center Workers Get Pounded, Pampered|work=[[The Wall Street Journal]]|date=2007-02-20|page=b1}}</ref> The computer company [[Compaq]]<ref>[https://web.archive.org/web/20070627063024/http://www29.compaq.com/falco/detail.asp?FAQnum=FAQ2859 Compaq FAQ: Where do I find the "Any" key on my keyboard]</ref> even edited their [[FAQ]] to explain that the "any" key does not exist,<ref name="Inquirer">{{cite news
