 The second function triggered by such a link is a global search inside your currently selected directory. It will merely take the link contents, place it in your search field and automatically "press Enter", to initiate the search.

When you click on it once, it will enter edit mode and reveal the title text and the internal link. Then, you can `Cmd/Ctrl + click` the internal link to trigger its functionality.
