The problem with leaving it as (1) is when command-key-is-meta set to 
t.  In that case, M-h never gets sent to emacs, but instead is sent to 
the application menu and causes emacs to hide.  It's not a standard 
binding, but I use it and I didn't want to prohibit it.  But in your 
case, it seems that command_key_is_meta is nil, so at the very least it 
should be...

	  if (NILP( Vmac_command_key_is_meta) || !(er.modifiers & cmdKey)) {

And next time I'll put the left brace on the next line to follow the 
coding standard...

The test you gave would send everything but C- and C-S- to the event 
manager.  I don't know the best way to go here.  It appears that control 
key sequences (at least C-S-) are used by the input methods to specify 
something and I don't know enough to say whether or not they should 
supercede emacs control-key sequences in general.  My ignorance of asian 
languages is showing.  Was this possible before, without 
USE_CARBON_EVENTS?

One possible solution  would be to introduce yet another variable, like 
"mac-ctrl-to-tsm", which would determine whether C- and C-S- key 
sequences would go to the TSM (and change the pen menu) or go directly 
to emacs.  Or there could be a lisp function that can send a keyboard 
event back to the event manager, so if specific control keys should be 
made to call back to the script menu.  What do other people think?
