// .NAME vtkInteractorStyleSwitch - class to swap between interactory styles
// .SECTION Description
// The class vtkInteractorStyleSwitch allows handles interactively switching
// between four interactor styles -- joystick actor, joystick camera,
// trackball actor, and trackball camera.  Type 'j' or 't' to select
// joystick or trackball, and type 'c' or 'a' to select camera or actor.
// The default interactor style is joystick camera.
// .SECTION See Also
