While Windows 8 may seem a bit out of place on hardware without a touch screen, trackpad gestures can help bridge the gap. Gestures on a trackpad work similarly to gestures on a touch screen.
Instead of moving the cursor to the corners of the screen, you can swipe the trackpad to reveal hidden menus and pinch your fingers to zoom in and out.

Trackpad Drivers
Laptops that come with Windows 8 should have trackpad drivers preinstalled and working properly. If you’ve installed Windows 8 on an existing laptop, you may have to install the trackpad drivers yourself, as many people are reporting that the final version of Windows 8 doesn’t yet include these drivers.
You may be able to download the appropriate trackpad drivers for Windows 8 from your laptop manufacturer. Many people have also reported that the generic Synaptics touchpad drivers, even though they’re for Windows 7, enable gesture functionality.
Charms
To access the charms bar wherever you are in Windows, place your finger at the right side of your trackpad and swipe inwards. The charms will appear at the right side of your screen.
You can also move your mouse cursor to the top or bottom right corners of your screen and then move the cursor towards the middle of your screen or press WinKey+C to access the charms.
Switcher
To access the new app switcher, place your finger at the left side of the trackpad and swipe inwards. The switcher will appear on the left side of your screen.
You can also move your mouse to the top or bottom left corners of your screen and then move your cursor towards the middle of your screen or press the WinKey+Tab keyboard shortcut to use the switcher.
Note that the switcher shows the entire Desktop, including all your desktop applications, as a single thumbnail. You can still use Alt+Tab to switch between desktop apps.
App Bar
Swipe down from the top edge of your trackpad to access the app bar, which contains an app’s options. For example, in the “Windows 8 interface” version of Internet Explorer, the app bar contains the address bar, tab thumbnails, and navigation buttons.
You can also right-click anywhere in an app or press WinKey+Z to reveal the app bar.
Horizontal Scrolling
To scroll horizontally, place two fingers on the trackpad and move them from right to left or left to right. Windows 8’s new interface uses horizontal scrolling in place of vertical scrolling, so this feels a bit more natural.
You can also scroll horizontally by scrolling the mouse wheel up and down.
Zoom In and Out
To zoom in and out, use a pinch gesture. Place two fingers on the trackpad and move them towards each other to zoom in or move them apart to zoom out.
You can also hold the Ctrl key and scroll your mouse wheel up and down or hold down the Ctrl key and use the + and – keys to zoom in and out.
Rotate
You can rotate the screen by placing two fingers on the trackpad and moving them in a circle, as if you were turning a knob. This gesture may be disabled by default in your touchpad’s configuration application, so you may have to re-enable it
You can also use the trackpad to move the cursor and control Windows 8 with a mouse. However, the gestures approximate touch better – swiping in from the right feels more natural than moving the cursor to the top or bottom right corners of the screen.
If you prefer using the keyboard, Windows 8 also supports a variety of keyboard shortcuts.
