The Control key is on keyboards and is labeled Ctrl. You use the Control key in the same way that you use the Shift key: Keeping it pressed down while pressing another character. The result is a Control key combination, which can have different meanings depending on which program is running. For example, in many word processing programs, CTRL + C will copy the highlighted text or object. On Macintoshes, the Control key is called an Apple key or Command key.
