You'll almost certainly want to keep an index for quickly jumping. To build the index, you would initially scan the attributed string. (Or, perhaps, you would build the index at the time you initially parse the text to figure out where to apply your attributes.) After that, you would probably observe the notifications from the text storage to update the index. > Thanks for any feedback.

That one is easy: -[NSAttributedString enumerateAttribute:inRange:options:usingBlock:].
