Pan
Touch and drag the page with one or two fingers. You can use panning to see another part of a page that has scroll bars. As an example, you can pan to see part of a long document that does not appear in the window. When you pan with one finger, drag your finger vertically to move the page. Dragging your finger horizontally selects text on the page.
Zoom
In order to zoom out, touch two points on the item, then pinch your fingers together. If you want to zoom in, touch two points on the item, and then move your fingers away from each other, as if you’re stretching them apart.
Switcher
If you want to access the app switcher, swipe a finger inwards from the left side of the touchpad. The switcher will then appear on the left side of the screen.
The switcher shows the entire Desktop, including all of your desktop applications, as a single thumbnail.
