Navigation inside note

I want to be able to define positions inside a note. Those may be for returning to oft-added, oft-modified positions of contents of a note.

Probably using dot commands.

.pos1

.pos2

.pos3

.pos4

.pos5

etc, scattered in different parts of the same note.

There could be a navigation scrollbar just left to the scrollbar of the note, where these positions are identified and you could quickly jump to particular positions by clicking on those position identifiders. This scrollbar can be turned on or off in Display Options.
