Implement keyDown: in the NSWindowController?

keyDown: only gets sent to the key view, whether or not it handles that keystroke. Since the method returns void, there's no way for AppKit to tell whether a responder handled the keystroke or not, so it can't pass it up the chain.

I'm not seeing a reason why
you need performKeyEquivalent to catch unmodified Esc and letter keys...

Because -performKeyEquivalent:, on the other hand, does return a BOOL, so AppKit sends it to all the views in succession till one returns YES. But it only sends it to the window and views, not delegates.
