About Master Slides
Each Keynote theme includes a family of master slides (templates), each with its own
layout. Some master slides, for example, have only text; others have placeholders for
photos and other media.
You can change the master a slide uses at any time. For example, you might want to
change a large photo’s orientation from horizontal to vertical. To apply a new master
to a slide, select the slide, click Masters in the toolbar, and choose a new master slide.
You can also modify a master slide. When you modify a master slide, all the slides
based on that master also change. For example, you could add a logo to a master
slide and the logo would automatically appear on every slide—existing slides as well
as new ones—using that master.
For more information about changing a slide’s master and modifying master slides,
see Keynote Help or the Keynote User’s Guide.
