Is that auto pilot disconnect, when was it disconnected?

Before I flew night freight I wouldn't have belived disconnecting the Auto pilot would be so challenging. However I remember once leveling off on departure in the early hours and then when we got further climb after winding in the new flight level not having a clue how to make the aircraft go up. I simply could not workout that I needed to select VNAV.
