Yes, I know that. I just thought there might be a work-around to get where I wanted to go (each # would be the chapter #).

I think I'll have to do something else. I've been looking at using a tab instead of the bookmark TOC or the table TOC (which I've been using). You can underline the tab space and that works pretty well except for this:

Chapter 1..........1
...
Chapter 10........10

It should look like this:
Chapter 1..........1
...
Chapter 10......10

I'm thinking I've got to either use a 01 number format (rather than simply, 1), or use a font (like courier new) where every character uses the same amount of space.
