I often need to check a term's usage within a given document. My current MO is to highlight the term and then do Ctrl-F. Most of the time the Navigation Pane toggles over to Headings, even if I already have it open and have the Results tab selected. Actually, ideally, I would completely remove the "Headings" and "Pages" tabs, as I have no use for them, but all I really would like to do is to have "Results" be selected every time I use Ctrl-F.
