## Detailed Description

KeySwitchMatrixManipulator is a decorator which allows the type of camera manipulator being used to be switched by pressing a key.

E.g. '1' for a TrackballManipultor, '2' for a DriveManipulator, '3' for a FlightManipulator. The manipulators available, and the associated switch keys, can be configured.
