How do you close all TOC's?
For example. I have the TOC from the Thompson Chain Archaeological Supplement open. I have numerous alpha headings open. "A" "E" "H" and so on.
Once these are open, it's tedious to have to then go to another topic in which that numeric heading is closed. You've been scrolling for ages just to get to "M".
Is there a way to collapse all?
I should also add. The last time I used the Thompson Chain was back in the day, many moons ago. My first Bible
1974ish. So forgive the ignorance on how to use this.
Chasing the rabbit. Every single time I open it, it still has that "smell" which takes me back. But I digress
