INTRODUCTION
An effective presentation gets your point across while holding the audience's attention. You can keep attention focused on your presentation by making the information on the slides stand out. One way to do this is to format the text. PowerPoint gives you many options to format your text, such as changing its font, style, size, and color.
TIP
Previewing the Font
When the Font dialog box is open and you have indicated your font changes, you can click the Preview button to review your changes before you accept them as final (in step 2). You might need to move the Font dialog box slightly out of the way to see the text.
