Bullets and Numbered Lists
Everyone makes lists. Word lets you make two types: bulleted and numbered lists.
A bullet is a dot or other symbol used to highlight items in a list. Use bullets to list items that do not have to be in any particular order.
Numbers (or letters) are used when information must be in a certain order.
If you don't care about the style of bullets or numbering used, you can turn on Bullets and Numbering by clicking on the appropriate button on the Formatting toolbar.
