2 fingers scrolling on Macintosh

This post will be my test post. And I was eager to present one of the greatest feature I use on my MacBook. It's the 2 fingers scrolling patented by Apple.
The principle really easy, instead of placing 1 finger on your track pad, place 2 finger and you can get great functions, you can scroll up and down, left and right.
If you keep your 2 fingers steady on the track pad and then you click, you'll get the equivalent of a "right click".
It takes a very short time to get used to it, but once you're done, you really can't stop using it. The "right click" feature is the most tricky to get right.
One thing that tells me that this feature is extremly user friendly is that now, each time I'm on an other laptop that does not have this feature I just can't stop trying scrolling with my 2 fingers, and the experience is exactly the same with all my friends using this great feature!
This might seems small peanut but this is a breliant idea!
