VR NAVIGATION

Pan: 

press and hold either left or right GR

Orbit: 

press both side buttons (GR) and rotate arms like you are steering a wheel

Zoom: 

press both side buttons (GR) and do the equivalent of the "pinch to zoom" on your phone except is with your hands. In other words, the further apart your hands go, the more you make the world larger and vice versa.

Note: if you zoom too much you might find yourself too far from everything else in the scene or "in the middle of nothing". In case this happen, just zoom back in or hit the "Home" button to go beck to standard position.
