All the existing slides are displayed in the slide list. Depending on the device orientation, the slide list can be located in different ways. When the device has a portrait (vertical) orientation, the slide list is located at the bottom of the screen with the slide editing area placed above. If the device has a landscape (horizontal) orientation, the slide list is located on the left and the slide editing area is on the right. Tap the necessary slide in the list to display it in the slide editing area.
To scroll the slide list, swipe left/right when the device is oriented vertically, or swipe top/bottom when the device is oriented horizontally. The slide indicator in the upper left corner of the screen shows the current slide number and the total number of slides in the current presentation ('n' of 'nn').
To zoom in a slide, use the stretch gesture: place two fingers on the screen within the slide editing area and move them apart. The indicator displays the current zoom value as you move your fingers until you reach the Maximum zoom level.
To zoom out a slide, use the pinch gesture: place two fingers on the screen within the slide editing area and move them together. The indicator displays the current zoom value as you move your fingers until you reach the Minimum zoom level.
If the presentation is zoomed in, you can scroll a slide swiping up/down and right/left within the slide editing area.
