I recently switched to Ubuntu and have been customizing all my settings as much as possible. Now, I'm not sure how I did it (since it was a while back ago) but in Windows 7 I found a way to make my desktop show when I two finger tapped the touch pad. It would also bring me back
So essentially, I would tap the touch pad with two finger and my desktop would show, when I tapped it again it would take me back to the window I was on previously.
Does anyone know how I could configure this?
Edit: I am using Ubuntu 14.04 on an Acer Aspire Timeline X. I can provide more details on my hardware if needed.
