Scrolling -- Vertical -- Through a Document by Screens 	
    
    You can scroll up and down within a document by moving your
    mouse pointer to the appropriate part of the Vertical Scroll Bar
    immediately to the right of the Document Window.  If the
    beginning of a document appears in the Document Window, click on
    any part of the Vertical Scroll Bar below the Microsoft Windows
    2.x Thumbwheel (small transparent box).  The next screen of
    information will appear.  If the Document Window is displaying
    text located within rather than at the beginning or end of a
    document, moving your mouse pointer to the area above the
    Thumbwheel (now positioned at the halfway point of the Vertical
    Scroll Bar) and clicking will move the document back a page
    (screen).  Clicking on the Vertical Scroll Bar below the
    Thumbwheel will move you forward a page in the active document. 
    When you are displaying the last screen of information of a
    document, the Thumbwheel will be positioned at the bottom of the
    Vertical Scroll Bar.  In this instance, if you position your
    mouse pointer above the Thumbwheel and click, you will move back
    a page (screen) in the document towards the beginning of the
    document.
