Apple command key

Apple computer keyboards also have a Control key near the Option and Command keys, as shown in the picture. The Control keys are found in the same location as the Ctrl keys on an IBM computer. However, when comparing functionality to Ctrl on a Windows keyboard, the command key is more similar.

Where is the Ctrl key on smartphones and tablets?

All Android devices, Apple smartphones (iPhone), tablets (iPads), and other mobile devices with touch screens don't have a Ctrl key. The Ctrl key is a modifier key that modifies the functions of other keys (e.g., keyboard shortcuts), which are not used with these devices.


With a computer on-screen keyboard, the Alt key is on both sides of the spacebar.

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 used "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.

Many notations represent the Ctrl key. Some documentation may also list commands, such as ^X, ^C, ^Z, etc., which means Ctrl+X, Ctrl+C, Ctrl+Z, etc. In other words, a user would want to press and hold the Ctrl or control key and then press the letter following the caret.

Below are example notations that represent pressing and holding down the Ctrl key and C key simultaneously. These notations are 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 indicating a control key combination.
C-c Emacs and Vim notation.
Ctrl/C OpenVMS notation.
