How to write or abbreviate Ctrl or control

When writing for a PC or IBM-compatible computer, the control key should always be written as "Ctrl" with a capital "C" and lowercase "trl." Early Microsoft documentation and computer keyboards did use "CTRL" but have since moved to using "Ctrl." When writing for an Apple computer user, "control" or "Control" should be used to prevent any confusion with them not having a Ctrl key.

As mentioned earlier, there are also many different notations that can be used to represent the Ctrl key. Below are example notations that represent pressing and holding down the Ctrl key and C key at the same time. These notations are used as shorthand in documentation and may be shown on computer screens when the Ctrl key is pressed.

Notation Description
^C Traditional notation that uses a caret (^) to represent the Ctrl key with the letter that is pressed in conjunction with the Ctrl key.
Ctrl+C Microsoft notation and notation used throughout Computer Hope.
CTRL-C Early notation used by Microsoft.
⌃C or Control-C Traditional macOS notation uses the "up arrowhead" character (U+2303, ⌃), followed by the letter being used, to indicate a control key combination.
C-c Emacs and Vim notation.
