The choice of location for the control key often comes down to the typist's hand shape and posture. Others leave the control key in the lower-left corner of the keyboard, and press it using the side of their palm. Keyboard layout preferences specifically to address this need are available in some operating systems. Some users of keyboards with caps lock on the left remap the keys to exchange Control and caps lock, finding the traditional location more ergonomic for using programs benefiting from use of the Control key. Other vendors produce keyboards for different computer systems with this placement of the Control key, such as the Happy Hacking Keyboard. The keyboards produced for One Laptop Per Child computers also have the Control key in this location. 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 traditional layout was preserved for later workstation systems and is often associated with Unix workstations. The keyboards of many early computer terminals, including the Teletype Model 33 ASR and Lear-Siegler ADM-3A, and early models of the IBM PC, positioned the Control key on the left of the keyboard, whereas caps lock resides in the same position on most modern keyboards.

When the original purpose of the ASCII control characters became either obsolete or seldom used, later software appropriated the Control key combinations for other purposes.ДЇurther information: Caps lock В§В Placement Modern keyboards distinguish each physical key from every other and report all keypresses and releases to the controlling software. In modern computers, the interpretation of keypresses is generally left to the software.

C, ASCII code 100 0011) or uppercase letters ( в‡§ Shift+ C, ASCII 110 0011) will generate the same ASCII code on a teletypewriter, because holding down the control key grounds (zeros the voltage on) the two wires used to carry the leftmost two bits from the keyboard, ignoring their modification by the в‡§ Shift key. Using the Ctrl key with either lowercase letters (e.g. Aptly, these characters are also called control characters. 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.

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. This allowed the operator to produce the first 32 characters in the ASCII table. On teletypewriters and early keyboards, holding down the Control key while pressing another key zeroed the leftmost two bits of the seven bits in the generated ASCII character.

Also, there is a standardized keyboard symbol (to be used when Latin lettering is not preferred), given in ISO/IEC 9995-7 as symbol 26, and in ISO 7000 'Graphical symbols for use on equipment' as symbol ISO-7000-2028. the German keyboard layout uses Strg as required by the German standard DIN 2137:2012-06. Abbreviations in the language of the keyboard layout also are in use. On keyboards that use English abbreviations for key labeling, it is usually labeled Ctrl (rarely, Control or Ctl is seen).

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

In computing, a Control key Ctrl is a modifier key which, when pressed in conjunction with another key, performs a special operation (for example, Ctrl+ C) similar to the Shift key, the Control key rarely performs any function when pressed by itself.
