Version 9 or the current version of the free "Adobe Reader" program should be used for best viewing of the PDF version. If needed, Adobe Reader can be downloaded here.
If you choose, the PDF can be viewed in FULL SCREEN mode. Use the "F11" key or click VIEW --> FULL SCREEN on your browser. Hit the ESC key to escape FULL SCREEN mode. The actual page size can be increased or made smaller by holding down the CTRL (Control) key as you scroll the wheel on your mouse forward or backward.
To go forward or back one page, simply click or right-click, respectively, anywhere on the page. Another option: At the top of the page, clicking the red arrows go back (left button) or forward (right) one page. Clicking the round blue buttons go to page 1 (left button) or the back page (right).
