OK, I just follow a recommentation from Garfinkel&Mahoney (Building
Cooca Applications A Step-by-Step Guide page 328) to split
the functionality into a controller and a document class.

But the First Responder does not have the desired actions.
I have added items to the File menus that are implemented
in the document class (formely the controller class) and
those actions are not listed when I ctrl-drag from the menu
item to the First Responder... Neither the File's Owner
of the ManiMenu.nib (which is NSAppliction) has (of course)
the desired actions listed.


Sorry if I'm being a bit stupid, but I really don't get
these things... And I really want to learn to be able to
develop Cocoa applications (and convert my existing
applications too).
