Master slides are a great new feature of Captivate 5.0. They are very similar to the Slide Master concept in Microsoft PowerPoint, and provide an easy way to add the same set of images to multiple slides. The way it works is this:
You create a master slide, and then add any required objects to it. The types of object you are allowed to add include text captions, images, highlight boxes, and rollovers. Unfortunately you are not able to add interactive objects such as click boxes or buttons.
