Martin, Ecir, and Quincey:
Thank you all! All three answers turned out to be helpful. (Quincey, you led me

I tried to use them once for underli
So I used DuckDuckGo to find "NSText syntax highlight," which led me to Uli
Kusterer's site where there an example syntax highlighting document project.
If I'm reading the code right, it appears Uli builds a new attributed string
with text colors and uses that to replace the original edited ra
