I have finished all of my slides...Now alls I need to do, is to set a 3 second interval of time in bewtween each slide so that I dont have to press anything......Then if i were to add music...how to I stop the music before the last slide plays (there is going to be a video on the last slide, so I need to stop the music........) anyones help would be appreciated

to set the time go to options>timing and type in 3
