press and hold either left or right GR
press both side buttons (GR) and rotate arms like you are steering a wheel
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.
