I think I know what you mean now. I am testing a small macro, or actually a routine, as part of another macro that tries to detect scene breaks and places a holder. It is not working exacly as I want yet, but it is almost there.
I'll place it online when it is done.
The dialogue macro is one of the macro's that I did not create alone. That one is due for an overhaul, so it is not available at the moment. I hope to have it in a working form in about 3-4 weeks. It handles dialogues in single quotes, double quotes (including low/high) and chevrons. If it is done, there will be a separate message thread opened.
