This is indeed the hard part. Compounded by the sad fact that some
(most? all?) terminal emulators can be configured to send arbitrary
stuff for a given key combo. For Xterm it's the Term.VT100.translations
X resource.

I fear you have no choice but to offer some heuristic which will work
most of the time (and be it: terminal? Only 32 CTRL chars for you!)
and a good instruction sheet for those users who are not the common
case.
