Recent Settings (D300S only)
(User's Manual – D300S page 337)
Recent Settings is very simple. This menu remembers the last
20 distinct changes you've made to your D300S camera. Each
menu selection that was modified is stored in a temporary
place called Recent Settings.
If you change something in your camera that's not already on
the Recent Settings menu, it will be added to the menu,
replacing the oldest change with your new one—at the top of
the list—if there is no room left at the bottom (i.e., you've
exceeded 20 items).
This can be a convenient way to find something you've
changed recently but have trouble remembering where it is on
the main menu systems.
