When adding links to sections in the current page, the UI may be a third tab in the Link popup (after the "Search pages" and "External link" tabs) called "Section link" (or similar). In this tab, the existing section titles would be listed (possibly in a hierarchical TOC fashion) and clicking on a section would add a link to that section.
