Interacting with the gizmo on a VR headset

On a VR headset, you can point the laser pointer at part of the gizmo, press and hold the trigger, and then move the controller to transform an object. For example, you can target an arrow to translate or target a circle to rotate.
If you point the laser pointer at part of the gizmo, and then press and release the trigger, you select that transformation axis. With a transformation axis selected, you can move the right thumbstick left and right to transform the object.

For the translate and rotate modes, you can transform an object in each axis individually. For the translate tool you can also drag one of the colored squares to translate the object along two axes. The scale tool scales objects uniformly along all axes.
