Custom Slide Shows, as indicated by their name itself, are Slide Shows customized by the user. The purpose of creating a Custom Slide Show is to display only selected slides from your presentation, without deleting the slides you do not want to show. To understand a Custom Slide Show, think of your individual slides as songs — then a Custom Slide Show is a playlist of those songs! Even better, since this is like a playlist, you do not have to delete the slides that are not used. And there’s more — you can create any number of Custom Slide Shows from a single presentation!
