Not aware of a sample showing this, but I'll try to explain what's
needed - assuming your using IB3/Leopard.
1) Add the menu item in your MainMenu nib. The title can be whatever,
the key should be the key you want to capture.
2) Select the First Responder in that nib. Open the "Identity"
inspector. Add an action in the "Class Actions" section at the top.
The name of the action doesn't matter, but it has to end with a ":".
3) Connect your menu item to the First Responder, to the new action
you added.
4) In your document class, implement the action.
When your document window is active, your document will be in the
responder chain and receive events. If it has implemented the actions
associated with the events, its implementation will be called unless
another object in the chain handles them first. Rather than say more,
the best thing is to look at http://developer.apple.com/documentation/Cocoa/Conceptual/EventOverview/EventArchitecture/chapter_2_section_6.html
for a more in depth explanation of how this works :)

Okay, I've been trying to get this working, but I'm not getting
anywhere. I think this is because I'm creating a document-based
application, and I can't figure out how to get the main menu to talk
to my document's view.
Does anyone know of a piece of sample code for getting key commands
and their associated menu items working in a document-based app?
This is a bit of a nightmare, right now, but I'm hoping it will
become clearer soon...
thanks,

the commands I have in mind change depending on the selected
object. Would that just be a matter of having different classes
handle the menu commands differently?
You can deal with that by using the NSMenu delegate methods, added
to Panther & later.
BTW, Are the menu key-commands set-up in IB, or are they coded?
You can do it either way.
