use of search/navigation bar - I want ordinary Find dialog

[LeoLes]

Friends,
In the old Word, CTRL-F popped up a little window that could be moved around and didn't get in the way. The new version opens a whole navigation window -- inconvenient because (1) it takes up valuable screen space (2) once I get to the place I'm looking for, I have to click near there in the document (otherwise it will go back to the previous place), then click the navigation window to close it. (The Escape key doesn't work anymore to close the Search window, it seems.) Also, the tiny little arrow Word used to have on the right-hand scroll bar that repeated your search is now gone. Can anyone advise me on:
1. How to reduce all this clicking back and forth
2. How to restore the little "search again" arrow to the side scroll bar,


3. Best of all -- how I would eliminate the Nav bar (which I don't like) altogether.
Many thanks!
