Light tap the track pad to simulate clicking
I'm coming from the MS Windows laptop. I noticed that I have to actually press the track pad (I'm not sure if that's what it's called) and simulate clicking. In the MS Windows side, I can lightly tap the track pad area and it would be a click. Is there a setting on the Mac OS X Lion or Macbook Air that would allow me to do this instead of hard pressing the trackpad for a click?
MacBook Air, Mac OS X (10.7.4)
