The Styles pane give you another way to work with styles. You can view a master list of individual styles, preview styles as shown in the document, disable linked styles, and manage styles. The Styles pane allows you to work with the main document styles, such as body and heading text. You can modify or delete a style, select all instances of a style, or add a style to the Quick Styles gallery. If you want to work with the more indepth styles that Word uses to create lists, comment text, footer, header, index, tables, table of contents, and other stylized elements, you can use the Manage Styles dialog box.
