Shortcut for swapping primary and secondary monitor?
*What's the shortcut/quick-key (or how do I create a shortcut) for switching between my two monitors?*
I ask this question primarily for a _Mac Pro using 2 Cinema Displays_. I realize I can open the preferences and drag the icons around to achieve this, but I really need a quick-key combination for swapping the two monitors on the fly, and quickly swapping back again.
I also use a Macbook Pro and an external monitor, and I imagine at some point it will be useful to use the quick-key on that too (ie. if I want to see some fine detail on the 24" display instead of the 15" display).
Can OSX 10.5.7 do this? Or do I need to upgrade? Or do I need a 3rd party application?
Mac Pro, Mac OS X (10.5.7), 2x Apple Cinema Display
