Has it ever happened that you wanted to include just a few slides in your slide show rather than displaying the entire presentation? Then you need not delete the slides that need not be shown — nor do you need to create a whole new presentation containing only the slides to be shown. All you need to do is to create a Custom Slide Show! So, what’s a custom slide show? Think of your individual slides as songs within a playlist — using the playlist analogy, your custom slide show is a playlist of those songs — you just substitute songs for slides!
