Yes and no, I've found several snippets but I haven't had a lot of luck testing
them. So far as I can tell what we're looking for here is the windows first
responder which by claim should be returned by either subleasing the window or
just calling [window firstresponder]. Unfortunately that seems to return the
highest responder (i.e.: the window itself or in one test just now a subclassed
view) but not the lowest element (which is what we care about) i.e. an
NSTextField. I'll do some more tinkering and see if I can't get back to you on
that.
