How Can I Scroll Faster Through Lengthy Documents?

Try pages view.

To access pages view

  • Tap the navigation box in the top right corner of the screen ( it's the four grey squares next to the magnifying glass). This opens the navigation panel.
  • Tap pages at the bottom left to enter pages view. 
  • The navigation panel can be minimized showing a window on the right side of the screen. From here you can scroll through pages while still remaining of full document view. 
  • Tap on the page you want to view and the document will jump to that page.
