What is the field code string for inserting a "last saved on" field that gives the current year only (no day, month or time)?

Thanks so much for any help provided.

You can add a formatting switch as follows:

{ SAVEDATE \@ "YYYY" }

To show/hide field codes, press Alt+F9. Edit the code as shown. Press F9 to update.
