I'm setup now to do 2 finger swipe back with the trackpad, but it only works in Safari. I want to enable swiping back (page back) in Finder, and the only way that seems to be work is to change it to 3 finger. When you do that, it disables the ability to drag with 3 fingers. I just switched from the magic mouse to trackpad. How do you drag things with the trackpad if you turn off the 3 finger gesture to drag? I can't seem to figure out how to do this.
