If the cursor is not yet initialized, MovePrev is identical to 
            MoveLast()()(). Otherwise, move the cursor to the previous
            key/data pair of the database, and store the secondary key and
            primary key/data pair in Current. In the presence of
            duplicate key values, the value of Current.Key
             may not change.
