 // A mock keyboard interface.
 // This class defines a pseudo keyboard device, which implements mappings from
 // a tuple (layout, key code, modifiers) to Unicode characters so that
 // engineers can write RenderViewTest cases without taking care of such
 // mappings. (This mapping is not trivial when using non-US keyboards.)
 // A pseudo keyboard device consists of two parts: a platform-independent part
 // and a platform-dependent part. This class implements the platform-independent
 // part. The platform-dependet part is implemented in the MockKeyboardWin class.
 // This class is usually called from RenderViewTest::SendKeyEvent().
