[car] @backwardok Just fyi, F6 is an ancient way of navigating larger areas ("panels", say) of some desktop apps. Kind of like a "meta tab key". It is still used by some Windows desktop apps. If you happen to have Windows 7 handy (I don't know if it's the same in Windows 10) you can see this by opening a File Explorer and selecting a random file in a random folder in the file system. Then F6 will navigate from the file system tree on the left, to the contents of the selected folder in the center table, to the table header filter, to the preview pane on the right, to the address bar, to the ribbon, and back around again. I seem to recall that F6 also would navigate to/from non-modal dialogs (like a find/replace, perhaps) but I can't find an example at the moment.
