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.
• See also Magnifying glass, Page to display, and Selecting text.
