Thanks. I then consider the behaviour on w32 to be a bug (if there is
no intention with this behaviour of course). What would other think
of this?
Sure it's a bug, but a bug of the OS. Setting w32-recognize-altgr to
nil appears to avoid this bug for people who don't need AltGr at all.
The bug is that Windows does not have a separate modifier flag for
AltGr, it uses Left-Ctrl + Right-Alt flags to indicate that AltGr is
being pressed. So we can't tell that Left-Ctrl is pressed when AltGr
is down.
If you can find a proper fix for this bug, we can probably get rid of
w32-recognize-altgr.
Have you thought about the possibility to use a low level keyboard hook?
I thought of this as a possibility for leaving the Alt key to windows
and still have a comfortable Meta key. <lwindow> and <rwindow> could be
used for that I believe but you must then use a low level keyboard hook.
The current approach with w32-pass-lwindow-to-system does not work as
far as I can see. If do
(setq w32-pass-alt-to-system nil), and then C-h c, <lwindow>, e
I get a Windows Explorer w32 window. Using a low level keyboard hook
this can be trapped.
However I do not know much about them. Can they be added if the user
have no privilege? As far as I understand it ought to be decided when
Emacs has keyboard focus and then it does not have it so that the
keyboard hook can be added and removed at the right moments. Can
WM_APPACTIVATE be used for this (or was there some other message)?
Otherwise there does not seem to be needed much code for the keyboard
hook itself and adding and removing it. And I guess the rest of the code
already is in Emacs?
