By "hex code" you mean "ascii char code", I guess.

Patches welcome, but note that unless you're running Emacs on a tty, C-/
and C-_ are two different keys/events.  And I wouldn't be surprised if
some terminal emulator out there also sends different byte-sequences for
those two keys.

I don't see why, really.  My main concern is to make sure the user can
run the command bound to those keys, and that doc should be appropriate
since the user can then try C-x u, C-_, C-/, and C--, all of which
should work, whether or not they generate the same byte-sequence.
