Keyboard key to temporarily toggle between Dashboard Preview & Design Modes

[David_Elston]

WHAT:

I would like to be able to temporarily toggle the Preview mode / Design mode on a dashboard by holding a key on the keyboard, (I suggest CTRL)

WHY: This would allow a model builder to...

• Quickly jump between the preview state and design state in order to view dashboard's final state, and then return to making adjustments. 
• Click an action button on a dashboard while editing it. Currently the model builder must click the toggle to go into "Preview" mode, click the action button, then reset the toggle back to "Design" mode again.
