Make sure your Adobe Reader tool bar has the ‘Page Display Toolbar’ enabled with the options ‘Previous View’ and ‘Next View’ selected. You can then retrace the links and return to your starting point. If you select the next or previous page you can still return to your starting point by using the ‘Previous View’ button.
If the next/previous page, or view, buttons are not visible they can be enabled by ensuring the ‘Page Navigation’ toolbar is turned on in the ‘View:Show/Hide’ menu. The individual buttons can be enabled by setting the options in the ‘View:Show/Hide:Tool Bar Items:Page Navigation’ menu.
