Goto Screen

The ePub Reader allows you to jump directly to any screen number you specify in the current chapter as you read an eBook. Tap on the screen position indicator at the bottom left of the screen to launch the Goto Screen dialog. The dialog allows you to select a new screen number by entering it directly into the text input area, by using the forward and reverse buttons, or by using the slider to select a new position. If you tap and press one of the buttons, the screen number changes quickly.
