>That'll do it.
Well, partially. Some editors have the ability to show the line numbers in a separate column on the left, and long ago I knew how to do that in fox, but haven't tried that for at least ten years and I'm not sure it can still do that. I sure can't :).
However, an important feature is still easy to access: rightclick, goto line. So instead of scrolling to see on which line your cursor is, you get to jump directly to the line you want. When checking the coverage for something, this helps a lot.
