Re: intercepting keydowns

Hi Roland,

Create a class that will act as a delegate for your NSTextView and hook
it up through interface builder. In the delegate implement one or all
of the following:

- (void)textDidBeginEditing:(NSNotification *)aNotification
- (void)textDidChange:(NSNotification *)aNotification
- (void)textDidEndEditing:(NSNotification *)aNotification

Hope this helps.
