Keyboard shortcut Browse revert to "B"
The short cut to use the save as feature and browse to a location previously was, alt+F > A > B.
It then changed to alt+F > D > O, and is now alt+F > D > Y1. Please change this back to B for Browse as the Y1 combination is slow and cumbersome.
F12 has been "save as" since before Excel 2003. It's one key!
