It's really quite simple. I just place two fingers together on the mouse pad and then slide left to right or up and down and then the screen scrolls. It's really cool because when I place one finger on the mouse pad it doesn't do it. I don't have to do that annoying click and hold and then slide. It's like I never knew I could do this but since this Mac informed me, I'm happy about this knowing this convenience.
I placed this top-of-the-line Mac on the camera program and then made it look like birds were dancing over my head. The guys in my room thought I was on drugs and hallucinating- it was really funny. They thought I was staring at pointless things and claimed that I was brain dead.
