Trigger/Simulate left mouse using right mouse

I actually want to use one mouse button for pan (which is there for left mouse button by default), and other mouse button to rotate around clicked entity.
I can rotate around using left mouse button with simply this line of code:;

But then I want pan using right mouse button. So I was thinking to trigger/simulate left mouse up/down event using right mouse up/down. How can I trigger/simulate left mouse up/down using right mouse up/down?

handler.setInputAction(function(movement) {

// Pick a new feature

var pickedFeature = viewer.scene.pick(movement.position);

if (!Cesium.defined(pickedFeature) || typeof(pickedFeature.content) == ‘undefined’) {



scene.screenSpaceCameraController.enableRotate = true;

var x = pickedFeature.content._model._rtcCenter3D.x;

var y = pickedFeature.content._model._rtcCenter3D.y;

var z = pickedFeature.content._model._rtcCenter3D.z;

pickedCenter = Cesium.Cartesian3.fromElements(x, y, z);;

}, Cesium.ScreenSpaceEventType.LEFT_DOWN);
