@WordsmithFL Use the built-in headings as you go to create an automatic index. (Check the Navigation box under the View Tab to see this.) You can edit the formatting of each heading level manually but don't do that while still writing the report. Format afterwards or simply choose a theme that you're happy with.
@danielbsmith Thank you. We're not quite at that point yet. The editor wanted me to reduce the word count by 10%-15%, which I'm doing now, then it goes out for external review. Once we have the final draft locked down, I'll index what's left. 😊
