Keary,
Thanks for responding. :-)
Your answer is what I was afraid of…
If “index” only applies to characters, and therefore index 0 is the position of the first visible character in the TextView’s NSAttributedString, I could iterate through, finding the range of each cell’s characters, then jumping to the next index after that and asking again.
That should work, but what the heck would I pass as the textBlock pointer? Since a text block is exactly what I’m trying to find, I don’t have a good pointer to start with, do I?

The documentation on how to create a text table (https://developer.apple.com/library/mac/documentation/Cocoa/Conceptual/TextLayout/Articles/TextTables.html) is fairly clear.
