If Access top item in MY MENU is selected for Custom Setting f1 (Custom control assignment) > Preview button, pressing the Pv button will display the top item in My Menu, letting you access functions that cannot otherwise be assigned to a camera control. Here is an example of how this could be used to configure the Pv button to display the Storage folder menu.
1 Add Storage folder to My Menu.
In My Menu, select Add items > PHOTO SHOOTING MENU and then highlight Storage folder and press .
2 Move Storage folder to the top of My Menu.
Select Rank items and move Storage folder to the top (you can reorder the items as desired at any time).
3 Choose a control.
Choose Custom Setting f1 (Custom control assignment) and select Preview button.
4 Select Access top item in MY MENU.
You also have the option of assigning Access top item in MY MENU to the Fn1 or Fn2 button, the Fn button for vertical shooting, or the center of the subselector.
You can now view the Storage folder menu at any time by pressing the selected button.
