How to Apply Bold, Italics, or Underlines to PowerPoint 2007 Text
PowerPoint 2007 provides four font styles you can use on your PowerPoint slides. Bold, italic, and underline are handy for emphasizing text. Regular is just PowerPoint’s way of denoting an absence of any font style
Italic: Italics are used for emphasis, when introducing a new term, and to mark foreign words such as violà, and Que magnifico! You can also italicize slide titles to make titles a little more elegant.
Bold: Boldface text calls attention to itself.
Underline: Underline text to call attention to it, but use underlining sparingly.
Select text and use one of these techniques to apply a font style to it:
Home tab: Click the Bold, Italic, or Underline button.
Keyboard: Press Ctrl+B to boldface text; Ctrl+I to italicize it; or Ctrl+U to underline it.
Mini toolbar: The Mini toolbar offers the Bold and Italic button.
Font dialog box: Choose a Font Style option in the Font dialog box. To open this dialog box, visit the Home tab and click the Font group button.
To remove a font style, select the text and click the Bold, Italic, or Underline button a second time. You can also select text and click the Clear All Formatting button on the Home tab.
