Pinch zoom. You can pinch (and reverse pinch) on the trackpad surface to zoom in compatible apps and experiences, such as a photo youre viewing in the Photos app.
Pan and scroll. You can use two fingers to pan and scroll. To pan, which is basically a horizontal scrolling (typical for multi-screen Metro-style experiences, including the Start screen), you drag two fingers from left to right (or vice versa) across the surface of the trackpad. Scrolling works as it does today: You drag two fingers up and down on the trackpad surface.
Charms. To display the Charms, you slide in on the trackpad surface from the right edge of the trackpad.
Switcher. To access the new Switcher interface, you slide in on the trackpad surface from the left edge of the trackpad.
App bar. To display an apps (or the Start screens) app bar, you slide in on the trackpad surface from the top edge of the trackpad.
Rotate. An uncommon gesture (and disabled by default), this lets you use two fingers to rotate an onscreen display, such as you might want to do in an image editing solution.
