Thanks so much for your fast reply, Cindi! Should I eliminate all guide words, or just those for the cell-5 headed sections where they aren't going to work? (I was inclined to just eliminate them for the sections in which they aren't useful, and put a TN after the heading saying as much.)
Also, do you think I'm doing the right thing by starting cell-7 headings on new braille pages, since that causes very blank pages sometimes? Or if I'm totally eliminating guide words, is that not necessary?
