The Control key is located on or near the bottom left side of most keyboards (in accordance with the international standard ISOIEC 9995-2 ), with many featuring an additional one at the bottom right.

Abbreviations in the language of the keyboard layout also are in use.

German keyboard layout uses Strg as required by the German standard DIN 2137:2012-06.

Also, there is a standardized keyboard symbol (to be used when Latin lettering is not preferred), given in ISOIEC 9995 -7 as symbol 26, and in ISO 7000 Graphical symbols for use on equipment as symbol ISO-7000-2028.

This allowed the operator to produce the first 32 characters in the ASCII table.

These are non-printing characters that signal the computer to control where the next character will be placed on the display device, eject a printed page or erase the screen, ring the terminal bell, or some other operation.

For example, the character or G, whose ASCII code is 71 in base 10, or 100 0111 in binary, would be transformed into the binary code 000 0111 (7 in decimal), which is assigned to the bell character.

In modern computers, the interpretation of keypresses is generally left to the software.

Modern keyboards distinguish each physical key from every other and report all keypresses and releases to the controlling software.

The traditional layout was preserved for later workstation systems and is often associated with Unix workstations.

Keyboards from Sun Microsystems came in two layouts; Unix and PC-style, with the Unix layout having the traditional placing of the Control key and other keys.

The keyboards produced for One Laptop Per Child computers also have the Control key in this location.

Other vendors produce keyboards for different computer systems with this placement of the Control key, such as the Happy Hacking Keyboard.

Keyboard layout preferences specifically to address this need are available in some operating systems.

Each notation below means press and hold Ctrl while pressing the X key.

In newer games, the key is often used for crouching instead.

The original Apple mouse design reduced complexity by only offering one button.

As the interface developed, Contextual Menus were offered to access extra options.

On Unix and Windows, the user had other mouse buttons to use.

Apple calls this a secondary click as left-handers can choose which side this button is on.

Keeping it depressed while sending information to the Quickbooks servers fixes the errors.

For example, Ctrl-A moves the caret to the start of the paragraph, Ctrl-L vertically centers the current line in the editing field, Ctrl-K cuts text to the end of the line to a kill ring separate from the normal clipboard, etc.
