Control-X

{{short description|Computer command}} {{about|a key combination|the control character, CAN|cancel character}} In computing, ''Control-X'' or ''^X'' is the key combination of the control key and a key usually labelled "X", typically used to cut selected text and save it to the clipboard ready to paste elsewhere. There is some disagreement whether the action moves with the key labelled "X" or stays in the lower-left location on keyboards with different letter arrangements.{{cn|date=May 2024}}

On Mac OS X {{Keypress|Command|x}} has an analogous function.<ref>{{cite web |url= http://support.apple.com/kb/HT1343 |title= Mac Keyboard shortcuts {{!}} -23}}</ref> The key combination was one of a handful of keyboard sequences chosen by the program designers at Xerox PARC to control text editing.{{citation needed|date = January 2013}} This style of human–computer interaction is referred to as '''indirect manipulation''' as opposed to direct manipulation. Direct manipulation is a term introduced by Ben Shneiderman in 1982 within the context of office applications and the desktop metaphor.<ref>{{cite journal|last=Shneiderman|first=Ben|title=The future of interactive systems and the emergence of direct manipulation|journal=Behaviour & Information Technology|year=1982|volume=1|issue=3 |pages=237–256|doi=10.1080/01449298208914450}}</ref><ref>{{Cite journal |last= Shneiderman|first= Ben|author-link= Ben Shneiderman|title= Direct Manipulation.

On ASCII terminals the key combination produces the CAN control character. Before the standard use for "cut" it was used for a variety of different purposes by different software. Emacs uses it as the first keystroke in a number of two-keystroke commands, for instance {{keypress|Ctrl|X}}{{keypress|S}} saves the current file.
