I will be getting training online where I will view another person's screen using Yugma and will be performing the actions I view on my system in another app. I guess the best way to do this would be dual monitors but I have the Mac Mini. My desk doesn't have room for two monitors anyway. I need to see both screens full size. Is there some way to quickly switch back and forth between two screens? I tried Expose, but it keeps shifting the position of the windows which slows down the process of switching.
