When using the Windows Phone emulator pressing the Pause button activates the hardware keyboard that you can use in place of the on-screen keyboard emulator to interact with the application. A little-known detail is that if you turn on this feature the OrientationChange event is no longer generated until you restore the software keyboard back (this is by design) This detail has made me spend a moment of panic yesterday so I wanted to share it.
