Problem

It is common to want to go back to the previous point in the document you edited and then back to the current edit point. These are often widely separated. Keyboard shortcuts for this would be useful.

Proposal

Introduce a history of edit points per document.
Introduce a "previous-edit-point action with keyboard shortcut to scroll the previous (non-consecutive?) edited line on screen.
Introduce a "next-edit-point" action with keyboard shortcut to scroll the next (non-consecutive) edited line on screen. If the currently edited line is the latest one, it would be scrolled onto the screen if necessary.
