I've just switched from a Dell XPS 13 to a Lenovo T480s, and I'm not liking the way the touchpad works. On the Dell, I could tap-click anywhere and it would be the equivalent of a left click on the mouse. On this Lenovo, it seems to be attempting to emulate all three mouse buttons.

Is there a way to disable this 'three button' functionality, or do I just have to get used to it?
