Forward Button Message
In '09 there was a setting you could put on forward button. You were able to force people to go through the slides and only go allow them to go back not forward and it would display a message: "You may only view slides you have already viewed" if they tried to move forward before time for each slide was up.
I can't seem to find this anywhere in '13 and when you restrict so they must move through slides you don't get a message - is this still available in '13? I searched forums but can't seem to find anything.
