Is it possible to set a place holder in a large document so I can return to a specific place in the document with one click or hotkey?

For example, when adding new content to Section 2.5.7, I need to search through the document for something. So I set a placeholder in Section 2.5.7, do the search, and (after finding what I was looking for) press the hotkey to return to the placeholder in Section 2.5.7.

Thanks.
