6. 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.
7. physiology regulation or maintenance of a function or action or reflex etc; "the timing and control of his movements were unimpaired"; "he had lost control of his ">sphincters"
