Removing "return TRUE" and instead doing
bHandle = NILP(Vw32_pass_alt_to_system);
break;
made this work as Jason suggested. I.e. it allows the use of Alt-TAB
as M-TAB on w32. (The back draw is that you then can not switch to
other applications using Alt-TAB when in Emacs.)
Other application will still respond the normal way to Alt-TAB.
I must say again I am surprised that this worked. I wonder though is
this is documented behavior. If it is, then maybe it is time to
include the low level keyboard hook in Emacs? (I myself does not like
this behavior, but others might want it.)
