I use full-screen app mode often. I also switch between my magic mouse and the laptop trackpad often. The Mac preferences allow me to use 3 or 4 finger swiping on the trackpad but only 2 finger on the magic mouse. I really want the same gesture for both devices. I don't want to think about what tool I'm using. To me it should just be the same! Is there a way to do this using better touch tool? I haven't been able to figure out the correct action?
