This is all theory, and I have not had to do this, but if it were me I would look at the methods with the words "lineFragment" in them will help isolate the line. I imagine that once you get the glyph nearest the insertion point, you should then be able to use lineFragmentUsedRectForGlyphAtIndex:effectiveRange: and passing its return value to -setSelectedRange:. That should at least get you close if it doesn't do the trick. Also, if you didn't notice from another responder, you can get the appropriate NSLayoutManager from the NSTextView itself.
