Try it and see. Let's say we want to catch Esc directed to the window as a whole (to exit full screen mode, if I recall your example). So what I would do is to insert an NSResponder instance behind the window in the chain and implement keyDown:. When an event arrives (arrives! It got here by being handed up thru all the views and the window, which therefore clearly didn't handle it), we look to see if it's for us - i.e., is it Esc or not. If it is, we tell the window to do what it's supposed to do, and the event is not handed any further up the responder chain. If not, we pass the event to super and the event is handed on up the responder chain in the usual way, and proceeds to the window controller and so on. I've been using this technique for many years and haven't had any trouble with it. It seems to me that this is just what the responder chain is for. m. -- matt neuburg, phd = [EMAIL PROTECTED], <http://www.tidbits.com/matt/> A fool + a tool + an autorelease pool = cool!
