I either use an icon in the dock or I start Emacs via a Shell script:
cat `which emacs`
#!/bin/sh

test -x "$emacs" ||
emacs="$HOME/local/opt/emacs-23.1/nextstep/Emacs.app/Contents/MacOS/Emacs"
test -x "$emacs" || emacs="/usr/bin/emacs"

exec "$emacs" ${SSH_CONNECTION:+-nw} ${SCREEN_IN_SSH:+-nw} "$@"

Both behave exactly the same.

Here you are...

It's in the menu bar, just like a native OSX application.

Still have to look into those.


If I hit AltGr-Backspace and do the C-h l afterwards I see:
M-(sharp s) C-h l
(I can't insert the real sharp s in this emacs, I currently use to type
this post, but it is displayed as a "normal" sharp-s in the help
buffer).

Another thing I noted: the described behavior occurs with that keyboard
layout I loaded from the net as well as with the original osx layout.  I
toggle those using a little icon in the menubar and applications like
e.g. the terminal that shipped with this computer reflect the changes
immediately: with the original layout I see a question mark upside-down
if I hit AltGr-Backslash but with the custom layout I get a backslash.
Funny, that makes no difference in Emacs.

xev didn't help either.  It reports AltGr as 

KeyPress event, serial 26, synthetic NO, window 0x600001,
    root 0x27d, subw 0x0, time 4154597274, (135,83), root:(135,105),
    state 0x0, keycode 57 (keysym 0x20, space), same_screen YES,
    XLookupString gives 1 bytes: (20) " "
    XmbLookupString gives 1 bytes: (20) " "
    XFilterEvent returns: False

with the original layout and as

KeyPress event, serial 26, synthetic NO, window 0x600001,
    root 0x27d, subw 0x0, time 4154673256, (86,89), root:(86,111),
    state 0x0, keycode 69 (keysym 0xff7e, Mode_switch), same_screen YES,
    XKeysymToKeycode returns keycode: 66
    XLookupString gives 0 bytes: 
    XmbLookupString gives 0 bytes: 
    XFilterEvent returns: False

with the custom layout.  However, since X11 was launched when I started
xev that's probably not releveant anyway. 

Well, that's it.  I'm running out of ideas what else to try (other than
compiling Emacs from CVS maybe).  Is this considered a bug, shall I sent
that report?


Kind regards,
Stefan
