Hey, where's the button? The amazing new trackpad doubles as a button â" just press down anywhere and consider it clicked. No separate button means there's 39 percent more room for your fingers to move on the silky glass surface. Now that Multi-Touch gestures have come to MacBook, all the function is in your fingers. Use two fingers to scroll up and down a page. Pinch to zoom in and out. Swipe with three fingers to flip through your photo libraries. Rotate to adjust an image with your fingertips. Using the new four-finger swipe gesture, swipe up or down to access Expose modes and left or right to switch between open applications. If you're coming from a right-click world, you can right-click with two fingers or configure a right-click area on the trackpad. The more you use the Multi-Touch trackpad, the more you'll wonder what you ever did without it.
