Here is an example of setting 'static 0' (Animating on) via a cm2 file. This is only a partial pose, it only affects yOrbit (rotateY) of the Main Camera. The k value is 45.0, the staticValue is 90.0. In P6, this pose will unconditionally set the k value to 45°, irregardless of the state of the Animating switch in the interface, and it will remain at that value when the switch is toggled.

As this pose only affects one channel it could leave rotateY in a diffrent state to the other channels in the main Camera. So you may need to start a new scene after using it to be sure your camera is returned to its normal state.
