- The Ctrl key is used in combination with letter keys and keys like Break,
- NumLock, and Return, to indicate that the Ctrl key is to be held down, and
- WHILE HOLDING IT DOWN, the other key is to be pressed. Ctrl-A through Ctrl-Z
- are used to enter the control characters. See the ASCII definition for a
- list of the control characters. A few Ctrl key combinations are commands to
- DOS, as follows. Not all of these are always present, and others may do other
- things on your computer. The Ctrl keys are explained in more detail in the
