Control key chart
Some application programs can 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 programs that use this system cannot use control-@, and
many programs use the control keys for other purposes.
