- The arrows on the left allow you to flip through pages without scrolling.
- You can go directly to the page you left off by inserting the page number you want after the word 'Page.'
- The - + symbols allow you to zoom in and out.
- The final symbol on the right expands the page to full size.
- You can scroll as well as flip through pages depending on your comfort level.
- The mobile version is a normal sized pdf stripped of any web graphics to make the loading faster. It can be used for PC reading as well if you prefer scrolling to page flipping. I find the vertical layout cumbersome for reading on PC but others may not.
