You can use two fingers on the track pad to scroll up and down windows, web pages, maps and so on. Position your pointer on to an object such as window title bar, or image on your screen, then press your finger on the touch pad until you hear a click, then without releasing your finger, drag across the track pad to move the object. Just tap both fingers on the pad at the same time. This is like the right mouse button and can be used to right click on objects such as icons to reveal a context menu of options. This is like your left mouse button and can be used to select objects such as icons or text fields on the screen. These gestures make it easier to interact with the interface. If you have a Chromebook with a trackpad, you can use various finger gestures to operate certain features of ChromeOS.
