Size of display image

To the left of the scroll bar at the bottom of the document window is the Document pop-up menu for controlling the size of the displayed page and how the vertical scroll bar works.  You can choose any of three viewing modes:

• Document:  scroll from one page to the next, through the entire document.
• Single Page:  scroll from top to bottom of the current page only.  Use the Page pop-up menu or its arrows to change pages.
• Thumbnail:  scroll through the entire document; the image is reduced to 33%.  More than one page is displayed at a time.
