"I'm just diving into the NSTextView and I'd like to write a small wiki type system (very similar to VoodooPad actually but with a few twists). I believe I get how I'd actually convert all WikiNames? to links, but I'm not real sure where in the pipeline to place this code? I'm assuming for efficiency this should really by done by watching text as it's typed and adding the link attributes as needed. Which delegate would be appropriate for basically watching the text as it is typed? Or, is there a better way?"
