There's two things to know here...

First, in IB you can add actions to the "First Responder" class.  It's
not a real class, but adding methods is the same as for a "real" class
in IB.  Select the First Responder, go to the Classes tab, bring up the
Attributes Info, and add.

Second, The NSWindowController of a window, if it has one, is the
window's nextResponder.  And, if the NSWindowController has an
associated NSDocument, although NSDocument is not an NSResponder, it
will also get a chance to handle action messages.

So, declare the method on First Responder in your main nib, wire the
menu command to it, and then implement the action in your
NSWindowController subclass or your NSDocument subclass.
