Your best bet is probably to retarget the Paste menu item to use a different

Thanks Kyle,
Unfortunately the standard paste: selector is used extensively elsewhere in
my app, so this simple solution would not be so simple. This is an otherwise
very self-contained modal dialog that doesn't have much to do.
The good thing about this solution is that it does fall back to sending
-paste:. But you are right; it does seem a bit heavy-handed for your localized
need.
I solved it as follows:
My window controller, which is the window's delegate, implements
-windowWillReturnFieldEditor:forObject:. I return a subclass of NSTextView
which overrides -paste: and adds a property, -pasteDelegate: which I set to
be the window controller. (I believe the FE's nextResponder is usually also
the windowController, but I wasn't entirely sure I could rely on that, so I
just added an extra property to hook it up). Then I just punt -paste to the
-pasteDelegate (and also -validateMenuItem for that action).
Cool. In order to avoid a retain cycle or a dangling pointer, instead of using
a pasteDelegate (since there's no clear place to nil the property out) I would
probably just use [[self window] windowController].
