Re: OS X System Key Combinations

Hi, Pete.

The command key is the Emacs super key here.  The option key is the Emacs meta key.  The control key is, of course, Emacs control.

In the Emacs system preferences, for instance, I have a service which inserts a date stamp.  This service is bound to command-option-control-d.  The service is defined and available for all applications (not just Emacs).  It, along with all of the other combinations defined there, works fine with my other applications.   But Emacs reports:

<C-M-s-268632068> is undefined

Which, of course, it is in Emacs.

Thanks again for the response.

Tom

With C-h k you can find out what alt-a and cmd-a are and you can also look via Emacs -> Services from the  menu bar at the services your Emacs sees. The modifier keys I mentioned have, presumingly, names like
