In computing, a control key is a key stroke, while holding down the Control key, with a special function.
For example, ctrl-a means "select all".
For ctrl-x, ctrl-c and ctrl-v, see also Cut and paste and Copy and paste.
See also : function key, keyboard layout.
Generally, the apple key on macs is equivalent to the control key; for example, apple+c copies, while apple+p prints. Same pattern for saving, cutting, and pasting. Exceptions do exist.
