Changing the Page

By right clicking the slide and choosing Slide / Page Setup you will have two important options. The first is the option to change page properties. Important page properties to change will be margins, orientation and determining what kind of presentation you will be making. The default Format is screen, assuming that you will be making the presentation to a computer screen. If you were making the presentation in a document format, like a letter sized page, you could choose the format that best fits.

When you review the background information you will see that the fill option allows for:

None

Color

Gradient
Hatching

Bitmap.

The preview gives you an idea of what it will look like.
