Hi everybody,
The XKB layout I’m using [1] defines an additional modifier, the
Navigation key. Whenever I press it, Emacs responds by beeping and
printing “<key-17> is undefined”. I can suppress this by
global-set-keying it to 'ignore, but this does not turn it off
completely. In particular:
* Hitting the key still interrupts Isearch, which is very annoying.
* M-Nav, C-Nav and C-M-Nav also need to be 'ignored, which does not
seem very elegant to me.
* Messages appearing in the echo area are nuked when I press Nav (this
is minor, of course, but you get the idea).
So, I’m looking for a way to make Emacs completely forget about the key,
to make it as no-oppy as Shift, Ctrl, etc., but I simply can’t find out
how to do this on my own. Could anyone give me a clue?
[1] <https://neo.eigenheimstrasse.de/svn/linux/X/de>; grep for Mod4
Thanks in advance,

I don't think I've ever been on a system that generates events like
<key-17>. What does Emacs display after typing `a', then the Navigation
key, then `C-h l'?
In any case, it looks like the Navigation key is not a modifier key like
Shift, Control, etc. So perhaps something like this will work:
(define-key special-event-map (kbd "<key-17>") 'ignore)
See the "Controlling Active Maps" and the "Special Events" nodes of the
Emacs Lisp manual.

Just the thing one would expect: a <key-17> C-h l.

Yup, that’s exactly what I was looking for, thanks a lot! It still
needs the same treatment for M-, C- and S-, but I can live with that.
Cheers,

Does `C-h v function-key-map' show a key sequence that is mapped to
[key-17]?

No, it doesn’t. I also tried (define-key function-key-map [key-17] [])
now, but it seems to behave exactly the same way as doing it in
special-event-map (i.e. I have to see about C-, M-, etc. myself). Is
there some more magic I’m missing?
