The page display and navigation area is located at the upper right corner of the window, below the menu bar area and above the graphics area.  It displays the page number that is currently on display and the total number of pages.  You can quickly move to the preceding or subsequent page (if available) by clicking on the Previous Page or Next Page buttons.

In addition, you can also enter a desired page number into the field provided in order to go directly to that page and display it in the graphics area.
