So when would you use a TC field? When most of your TOC entries are marked with heading levels, but you want to include an entry that doesn't have any formatting. Or when you want to include an entry from the middle of a sentence or paragraph. Another great time to use TC fields is when you've inherited a poorly formatted document that needs a TOC; it will be quicker to add TC fields than to reformat the document properly with heading styles.
Here's how to mark text with a TC field:
- Select the text.
- Press ALT+SHIFT+O.
- Fill in the Mark Table of Contents Entry dialog box (see the picture on the left).
Although you could create an entire TOC by manually marking text with TC fields for inclusion in the TOC, you run the risk of making an error — and it will take an awful lot of time. Instead, use a built-in method of marking the text (like heading styles) and use TC fields only when necessary — for example, if you want to mark text but not change its formatting or style.
