Greetings,
 
Get yourself an ascii table.  Here's a pretty one but you can google
for others if you like.

The first column shows the control codes produced by the alpha keys
in the third column.  The keys in the second column don't produce
control codes.  The lowercase keys either don't produce control codes
or produce the same codes as the uppercase key.  I'm not sure which.

For example, the Z key (132 octal) produces the SUB control character
(032 octal).
