In more comprehensive notes, I solve this by moving into an external editor. But maybe, this is not necessary: Are there bookmarks in editor available, like SHIFT F2 (set/unset) and F2 (goto) in notepad++ ?
I am collecting footnotes or hyperlinks at the end of notes. Therefore, it would be handy to have a »back to stored position in current note«. Typically, a single position would be enough.
