[syn: {master}] From The Free On-line Dictionary of Computing (13 Mar 01) [foldoc]: control(Or "ctrl", "^") One (or a pair) of {modifier keys} found on all modern {keyboards}. If the control key is held down while pressing and releasing certain other keys then a "{control character}" is generated, e.g. holding control and hitting A" generates control-A ({ASCII} code 1). The ASCII code for the control character is generally 64 less than that for the unmodified character. The control key does not generate any character on its own but most modern keyboards and {operating systems} allow a program to tell whether each of the individual keys on the keyboard (including modifier keys) is pressed at any time. Control characters mostly have some kind of "non-printing" effect on the output such as ringing the bell (Control-G) or advancing to the next line (Control-J). Most have alternative names suggesting these functions (Bell, Line Feed, etc.). See {ASCII character table}. (1997-07-10)
