For assistance with setting up numbering, see the article written by Shauna Kelly (the link has already been posted here).



Are you saying that you want only part of the paragraph to be formatted as a heading (and included in the TOC, if there is one)? In that case, insert a style separator, for example using the shortcut Ctrl+Alt+Enter.

When working with style separators, you may want to display nonprinting marks, because that makes things a lot easier. "Ordinary" paragraph marks are represented by pilcrows, ¶, while style separators are represented by ¶ characters surrounded by a dotted line.
