I have a very long page that I don't want to break up into multiple pages for a number of reasons. Whenever I am reading it and find something I want to edit, the editor always jumps to the bottom of the page and I have to scroll back up and find the place I wanted to edit, which often takes a little while.

Is there any way to get the editor to start at or near the location that was being viewed, or may there be some sort of "edit here" context popup that I haven't found? or an ability to edit sections/subsections individually, like in MediaWiki?
