Adobe pdf files are viewable using Adobe Acrobat Reader within Netscape and Internet Explorer windows. An additional toolbar is provided within the Reader window, and an example can be seen in the image below.
This toolbar contains buttons for navigating and controlling the viewing of the pdf file so that you can (among other options):

• zoom in and out
• pan around the image
• search for text
• use bookmarks to jump to specific sections
• print out part or all of the document.

Adobe Acrobat Reader 4 Toolbar Help

Descriptions of individual icons on the toolbar:

Find and Find again icon: Search for specific words or phrases in the document. The Find Again button goes to the next occurrence of your specific text in the document.

Save icon: Save a copy of the pdf document on your hard drive.

Printer icon is used to print part (choose Current Page or a range) or all of the document.

Pan icon: Once selected, your pointer becomes a hand. Click and hold down the hand pointer anywhere on the document and drag the mouse to pan up, down, and around.

Zoom-In/Out Tool icon: Choose this icon to access a "magnifying glass" which when clicked on the document will cause it to magnify. To zoom out, you can hold down Ctrl > Shift and click the document again (now the tool will show a minus sign (-) rather than a plus (+ ), or click the Zoom-in icon and hold until submenu shows which also contains the Zoom-out icon.

Show/Hide Navigation Pane icon: Toggles the Index view along the left-hand side - click once to remove the Navigation (index), click again to bring it back.

The toolbar at the bottom of the screen also controls the zoom of the view. The small arrow beside the 99% in this example will display a dropdown menu for your choice of sizes. Choose a viewing percentage (usually 100%). This toolbar also gives you the current page number (1 of 20 in this instance), and back/forward page buttons.

Goes to the first page of the document.

Goes to the last page of the document.

Back one page or Forward one page (or use the Page Up and Page Down buttons on your keyboard).

Go to previous view / next view (use to go back and forth between view settings)

Jump to preset view icons: They are Full Size, Fit-in-Window and Fit-in-Width views.

Rotate View icons: Use to rotate the document clockwise or counterclockwise for viewing rotated tables or landscape view portions of a document.

Another useful configuration is the view setting for page viewing. It is possible to view 1 page at a time (Single Page) that will jump from page to page when necessary, or have the document scroll as one continuous document page upon page (Continuous). Continuous-Facing shows multiple pages at a time at a reduced view that can be scrolled continuously.
