How to bind <lwindow>-; with a function on windows?

How to bind <lwindow>-; with a function on windows?

[anhnmncb]

When I type M-x global-set-key RET, then press <lwindow>, the help
window pops up and show:

<rwindow> runs the command ignore, which is an interactive compiled
Lisp function in `subr.el'.

It is bound to <mouse-movement>, <language-change>, <lwindow>,
<rwindow>.

I have no chance to press <lwindow>-; to function. Type them in emacs
window just produce a ;.

Some keys and key combinations on ms windows can not be used in
(unpatched) Emacs because they must be caught on a lower level than
Emacs currently binds them.

If you want to bind these keys then you can try the patched version of
EmacsW32+Emacs, see EmacsWiki.

If you put this in your .emacs:

(setq w32-pass-lwindow-to-system nil
       w32-pass-rwindow-to-system nil
       w32-pass-apps-to-system    nil
       w32-lwindow-modifier       'super   ;; Left Windows
       w32-rwindow-modifier       'super   ;; Right Windows
       w32-apps-modifier          'hyper)  ;; App-Menu (key to right of 
Right Windows)

then you will be able to use these bottom row keys as modifiers but you 
still won't be able to bind a function to the bare key (lwindow for 
example). You could however bind the function to Super- [a through z] or 
even combinations of Ctl, Meta, Super, and Hyper:

(global-set-key [(super w)] 'foo)

As Lennart notes there are some combinations that Windows will trap at 
the OS level but some of these are useful. Alt-tab will switch focus 
between emacs and some other app from which you may want to copy-paste 
for example.

There are more combinations than Alt-Tab that Windows will trap. For
example on my pc if I do

  (global-set-key [(super ?e)]
       (lambda() (interactive) (message "called super E")))

This does not work, lwindow+e will still show Windows Explorer.

That is correct according to MS documentation which says you can not
rely on rebinding lwindow/rwindow without a low level keyboard hook.
Sometimes it works, sometimes it doesn't.

True if you replace the first "sometimes" with "usually." Super (i.e. 
windowskey) d, u, f, r (all unshifted) also don't work but the rest of 
the combinations do. Alt-Tab can't be trapped but it's useful; Alt-F4 is 
fatal. Ctl-Esc brings up start menu but most if not all other 
combinations are open for Emacs use. In fact with the hyper key combos 
(appkey) I got H-whatever undefined with all tested key combos.

Wow, it works, many thanks.

Good. Btw, I was wrong about M-f4 (alt-f4)which seems to unconditionally 
kill the current process in Windows. In Emacs that doesn't happen. Both 
C-F4 and M-F4 can be mapped to functions.
