read-event question

read-event question

[Lars Magne Ingebrigtsen]

I'm having a really trivial problem, but I haven't been able to find
the answer in the Emacs or Emacs-Lisp manuals.  I'm sure I'm just
looking in the wrong place.

Here's the problem: I'm using `read-event' to, well, read a user
event.  I want to do something when the user enters `M-n', but I just
can't seem to find a way to translate `M-n' into whatever `read-event'
returns (or vice versa).

Using `read-event' and tapping `M-n' returns a large integer:

(read-event) => 134217838

Is there some function I can use to map [(meta n)] or whatever to this
number?

   (kbd "M-n")
     => [134217838]

Wow.

Anyway, perhaps the documentation to `read-event' should mention this?
Surely I can't be the only one who's wondered about this...

It seems obvious to me at least: the M-n keyboard event is a character,
and characters are represented as integers.  Have you read the Keyboard
Events node of the Emacs Lisp manual?
