Is there a special key, it also makes a larger trackpad surface, giving your fingers more room to move, click, and gesture. So trackpad supports multi-touch gestures you can use one or more fingers to interact with your documents, pictures and applications with gestures, such as effects, shock and rotating. Move up and down a document or Web page without any problems with the new built-in support for scrolling. And if the world comes from right-click, you can set, right-click on the trackball area, or simply press two fingers.
