The graphic show_navigation_button.gif shows the location of the Show Navigation button in the upper left corner of the browser window. Three buttons are included in all help windows, just below the Address bar. From left to right, they are: the Show Navigation button (shown in this graphic with the cursor pointing to it) is an icon that looks like a browser window with a frame that spans its left side; the Previous button is an up arrow; and the Next button is a down arrow. The same help topic in this example is Maintaining a question.
