I just noticed that Lenovo released a new driver for my W520 Synaptic touchpad.
The cool thing with this update is the Windows 8 integration, so now I can swipe from the right to the left and that will give me the charm bar or if I swipe from the left to right it will switch between my open applications. I can even swipe from the top down to get the application bar.
To get an idea what I’m talking about take a look at this video
This video will show more feature than I’ve got, so you have to test and see what your updated driver will give you
