Hi,

I've been messing about with this for a while
and have set up the bookmark exactly as
instructed using the \b switch.

to create a bookmarks, first you have to select text in the main
document, where the headings are. You must *not* select the TOC itself.
Then you have to create the bookmark (Insert | Hyperlinks | Bookmark |
Bookmark name | Add).
In the TOC field code you have to use the \b switch together with the
given bookmark.

To check, where your bookmarks start, and where they end, display the
brackets:
File | Options | Advanced | Show document content | Show bookmarks.

To select content of bookmarks: Insert | Hyperlink | Bookmark |
Bookmark name | Sort by Name | Go To.
(Maybe, you also want to see "Hidden bookmarks".)

When I generate the new TOC it creates it as is should;
however, when I update the other 'main' TOC the new
sections also appear here as well which is what I don't want.

Then you have to create another bookmark for the section, which should
appear in the main TOC. Or you have to use different styles.

I'd also prefer it if the new TOC doesn't
appear in the navigation pane, which it does,
presumably as it's using the Header styles.

The Navigation pane does not explicitely display styles, or headings.
"Outline levels" are shown in the Navigation pane.
