I'm not surprised there's no reference to the TOC8 Style in that dialogue. It has nothing to do with the heading, per se - it's a Table of Contents Style. Go to your Table of Contents and click on the paragraph break at the end of the 'Summary' entry, then:
• modify the alignment using the Ruler;
• right-click on the paragraph break; and


• choose Styles>Update TOC8 to match selection.

I think I know what you mean, but it's not where I am struggling. My problem is only in the navigation pane. The top "button" has a triangle and a horizonal bar. I'd like to to say "Table of Contents" instead. Second, the Summary-button is now a subsection of 7.9 and I'd like it to show up on the same level as the chapters, because it does not belong to a single chapter as it is a summary of the entire thesis.
