How do you create a slideshow where some slide transitions operate only on the mouse click [ie manually] while some sequences of transitions in the same show can be programmed to operate after a predetermined number of seconds? So far , I have managed to do one or the other but not a mixture in the same presentation. The customise each slide override option allows for longer or shorter transitions than the default setting but not a manual option - as far as I can see. Help , please ? Lee
