1. Title Case does ignore acronyms unless everything is in Upper Case; then it title cases everything (which is ok since how would it know it's an acronym)
Agree that it should not ignore words in quotes (wasn't exactly what I meant)
However, it works differently if Smarten Punctuation has been run, since while it handles a leading ASCII 34 correctly, leading curly quotes have a different result (Before-Quotes.jpg and After-Quotes.jpg)

2. When I do the above from the User Manual to get the green line and right click (TOC.jpg) I get options to [Reload], [Save Page], and [View Page Source], but I can't get anything to happen when I click them.
I was expecting that [View Page Source] would open the edit window to that point
3. TOC View (TOC View.jpg) does link to the edit window which conveniently allows me to fix/change the TOC source, but it's not clear what [Refresh] does.
[Edit] does open the TOC editor and I can rebuild/refresh using that
