Determining when an NSTextView is being edited?

I searched the archives and didn't find anything relevant to what I'm trying to do...

I have an NSTextView subclass. I want to override -drawRect: so that it does some additional drawing, but I want the drawing operation to take place only if the text view is actually being edited. The problem is, I can't find out how to get the editing state of an NSTextView class.

How do I get the editing state of the class? I already tried - selectedRange, but that appears to return a range even if the text view isn't being edited. I looked in the documentation, including the superclasses, and couldn't find an -isEditing method or something similar.
