The Contents button in the toolbar provides a table of contents for the entire W-2 Manual. The default view when you open the manual is to the "Contents" which shows the structure of the manual with a series of books, subfolders, and policy pages in the navigation pane on the left side of your browser and the Welcome page in the policy pane on the right side. To see this view after clicking on other views or searching, click on "Contents" in the toolbar.
