Quick way to toggle between "Larger Text", "Default", and "More Space" on Macbook Retina On Macbook's with retina display you are able to select between 4 different scale modes as showed in the picture below



It takes some clicks to get into the Display settings and choosing a new scale. I guess I am not the only one changing the scale frequently so I am confident that an easier solution to this exists. 

Question:
Are there any keyboard shortcuts that toggles the different scale modes without the need of third party software?
You can use Automator to script things like that since OS X does't include a built in command key for that option. Once it's scripted, you can then assign a key shortcut to that script/action.

Open automator and search for the "watch me do" action for scripting of the UI.
