Search within the content of a post in the editor. (ctrl+F browser search doesn't seem to cover it), and/or:

Is there a way to force the scroll position to be the same when you toggle from preview model to markup?

Use case is: making changes in a long/dense post. Hunting down the right spots to make changes in the dense and lengthy post is time-consuming. It'd be great to be able to search in the editor for a keyword (like a paper title) to more easily find and jump to the spots to fix. It's easier to find them in preview view, but I can't edit there, and when I swap back to markup, it jumps back to the top.
