The entire look of your presentation is dependent on the master slides, which are part of the presentation's theme. Master slides are templates for each of the different kinds of slides in your presentation. Master slides define slide attributes such as the title and body text box layouts and default font styles; the slide background; the default bullet styles; styles for charts and tables; and the type of slide transitions.
When you create a new slide, Keynote copies one of the master slides, and the objects (text boxes, pictures, tables, or charts) from the master slide are placed on the new slide. Then all you need to do is put content into the text boxes or graphic boxes.
Most of the time you'll use master slides without modification, but Keynote allows you to customize master slides within your presentation, to account for your presentation's special needs.
In this chapter, you'll learn about the different master slide types, as well as how to apply master slides to your presentation's slides and change master slides.
Master Slide Types
Keynote themes can contain any number of master slides, but in most themes, you'll find at least 11 master slides, because that's how many master slides are included in most of the built-in Keynote themes. Themes aren't required to have 11 master slides; the lower limit is just one master slide, and I've seen themes from third-party developers that had 45 master slides from which to choose.
Most of the themes that you'll be working with will, however, contain the basic set of 11 master slides, as shown in Table 3.1. This set contains the master slides that you will use most often, so you should become familiar with them and how they are used.
