If you haven't bothered to format your document at all, or if you received it in ASCII (text-only) format via email, Word's AutoFormatting feature may be able to handle the formatting for you. Among the tasks AutoFormat can perform are
Creating headings and lists, including bulleted lists
Applying styles to many document elements
Replacing ASCII text with custom symbols, including curly "smart quotes," fractions, ordinal numbers such as 1st and 2nd, em and en dashes
Replacing Internet and network addresses with hyperlinks (page 434) to the same addresses
To use AutoFormatting, choose AutoFormat from the Format menu. The AutoFormat dialog box opens (see Figure 8.19).
