I'm using Synaptics PS/2 Port TouchPad. I want to be able to switch between open windows (like Alt+Tab) by swiping three fingers left and right. I've been searching the deepest depths of the internet trying to make this work, but with no results. Anyone know how to do this? I'm using an Acer Aspire laptop with Windows 8.
I think you have a conflict of gesture-handling between Synaptics and Windows 8. Up-down three finger swipe is used by Windows 8 to manage the desktop.
If you turned off Windows 8 gesture-handling you might have a chance of getting Synaptics to work. Unfortunately, I don't have Windows 8 or a touch-screen to check this out.
I found this image for how this is done in Mouse Properties :
