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.

Hi, Bryan,
I'm not sure how to follow your advice. Do you mean that I should subclass NSTextStorage or create a delegate for it? The documentation states that textStorageWillProcessEditing "Informs the delegate that an NSTextStorage object is about to process edits."
If I should delegate, then from what to what?

I believe you have to work with the TextViews NSTextStorage object to manage this.
I believe the API you can use is "- (void)textStorageWillProcessEditing:(NSNotification *)aNotification"
Cheers,
Bryan

I have a simple Cocoa application with a controller and a window with an NSTextView. I want to intercept keydown events on their way to the text view, process them with a function or method, and send a possibly different keydown event on to the text view.
Nothing I try works.
Any suggestions?
