[vtkusers] vtk keyboard keys

[Cory Quammen]

I don't see that you are setting the interactor style in the
vtkRenderWindowInteractor.

You should have code like this somewhere in your example:

KeyPressInteractorStyle *style = KeyPressInteractorStyle::New();
vtkRenderWindowInteractor* renderWindowInteractor =
renderWindow->GetInteractor();
renderWindowInteractor->SetInteractorStyle(style);
