Function Keys F6

Pressing F6, in most applications, moves focus around the different panes on the screen. For example, F6 moves from the Slide Thumbnails to the Slide View in Powerpoint, F6 moves from the Find pane (when open) to the document in Word and F6 moves to the Ribbon in all Office applications, etc.
In Web browsers, F6 moves up to the address bar.
Pressing F6 cycles around different areas of an application, and pressing Shift + F6 cycles around in the opposite direction.
