I am wondering if something can be accomplished on the eDGes.

Flip the eDGe open, all the way so that the screens are back to back.
Have something on the LCD screen, while something else related is on the Reader screen.
Be able to change this (simultaneously on both screens) with the click of a button.

So, for instance, if I want to work on flash cards. The LCD screen can present "8 x 4 = ?" and the Reader screen can present "32" or "8 x 4 = 32" or somesuch.

But it would have to be quickly switched (simultaneously) to the next card with the click of a button.

How possible is that?
