How can I handle ESC key in Cocoa app?

Question

I made an app switching to full screen mode. I want to use ESC key to escaping fullscreen mode, but binding menu item to ESC key in IB is removed at runtime. How can I keep ESC key binding to a menu item?

Preferred way to handle escape key in Cocoa is this as like @Josh Caswell said.

#pragma mark - NSResponder - (void)cancelOperation:(id)sender {     [self exitFullScreen]; }
