So in order to stop using heading styles, let's say I have a book with chapters. I only want the chapter numbers and titles to show up in the TOC.
I use Header 2 from the home screen.

I think this is the point I must be going off track. When I begin a chapter, I just start writing and the triangles show up.

I need to know, if you don't mind, exactly what to do at this point so the header tri's don't show up.
