You won't find any pause() method because you can select at any time another 
one that doesn't read the mouse movement. You can learn from the 
osgGA::KeySwitchMatrixManipulator, which sets one matrix manipulator or 
another depending on the numeric key you are pressing:

osgGA::KeySwitchMatrixManipulator *keyswitchManipulator = new 

keyswitchManipulator->addMatrixManipulator( '1', "First manipulator", new 
MyManipulator1 );
keyswitchManipulator->addMatrixManipulator( '2', "Second manipulator", new 
MyManipulator2 );

viewer.setCameraManipulator( keyswitchManipulator);
