I know how to switch between them but on my brothers macbook he can switch between windows and os x but swiping on the touch pad on his MacBook Pro which is a 15" i6 MacBook Pro is their away to toggle keyboard or touch pad to switch then ?
If using Parallels or Fusion, thats possible. Both are called hypervisors and run like an app in a separate window when OS X is running. It's easy to go back and forth between Windows and OS X.
