Indeed we added a possibility to keep the Backstage control opened when the Escape key is pressed. In Q3 2013 we exposed the HandleKey() protected method of the RadRibbonBackstage control. In order to achieve your requirement you can create a class that derives from the RadRibbonBackstage and override its HandleKey() method. The following code snippet demonstrates sample implementation that will keep the backstage open even when the Esc key is pressed:
MyBackstage : RadRibbonBackstage
I hope this helps.
