Unfortunately, the navigation isn't very smart yet. When jumping to the previous/next mark, the window area merely scrolls such that the marked line becomes visible.

It would be much nicer if

• the line was highlighted (briefly) after the navigation action – this would make it easy to immediately find the marked line visually.
  A temporary highlight effect should be used to visually guide the user to the target line.

How do we reconcile this with FTCS style marks, with a prompt/command/output section? Do we select just the prompt? The command? The whole blob?

What about for multiline marks?

• crawl: a rect with just from the start->end points of the mark, regardless of how ridiculous that looks
• walk: a bunch of rects for each line
• run: rects for each line, with intelligent borders so the border is only around the actual marked text
