Control Key Chart
Some application programs use control key codes for decimal values
O-27. The table below gives you the proper values. The Control Key
column indicates that you press the control key at the same time
you press the key for the letter or symbol in that column. For
example, you press the control key and A at the same time to send
the value 1.
Some application programs that use this system cannot use
Control-@, and many programs use the control keys for other
purposes.
