One TOC can have text marked by three methods: heading styles, outline levels, and TC fields.
Now that you know all about the fields that are working behind a TOC, remember that it's still just a TOC. You can format it in the normal way by applying one of the built-in formats that you learned about in the Tables of Contents I course.
And it's also good to keep in mind that the different methods of creating a TOC can be used in a single TOC. For example, you can have a TOC where most entries are marked with heading styles; where the headings that you don't want to use styles for are marked with outline levels; and where any key terms in the middle of paragraphs are marked with TC fields.
