Interacting with the gizmo on a desktop device

On a desktop device, you can left click and drag part of the gizmo to transform an object. For example, you can drag an arrow to translate or drag a circle to rotate. After you select part of the gizmo, you can also use the mouse scroll wheel 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.
