If you want a bullet style other than round black circles, do this:
Select the entire bulleted list. The bullets won’t appear selected.
Click Home, and then click the arrow next to Paragraph>Bullets.
Choose another bullet style from the Recently Used Bullets list or the Bullet Library.
Note: If the bullet you want isn’t in the library, click Define New Bullet, and then click Symbol, Picture, or Font to add a new bullet style to the library.
