This question is badly defined. What are your constraints? Is this meant
to be a human-readable program? If so, you need to stick to ASCII text
and probably want something like:
a A CTRL-A ALT-A
b B CTRL-B ALT-B
...
but I'm not sure what the point of that would be.
Normally, control-combinations generate control-characters. For example,
CTRL-M would normally generate a carriage-return character. Depending on
your needs, you can write this as any of the following:
a description: CTRL-M
an escape sequence: \r
caret notation: ^M
the standard abbreviation: CR
the Unicode display glyph: ␍
or an actual carriage-return character.
Note that in ASCII control characters only have a standard definition for
the following:
ctrl-@
ctrl-A through ctrl-Z
ctrl-[
ctrl-\
ctrl-]
ctrl-^
ctrl-_
ctrl-?
See here for more:

As for Alt-combinations, I don't think there is any standard for what
they are. I believe that they are operating system specific, and possibly
even program specific.
