Change this script to lerp euler angles?

I have a code that changes a certain variable in a certain code when you hold an input. Here's the script (it won't let me insert codes for some reason)...

var left : float = -0.75; //determines amount of zoom capable. Larger number means further zoomed in
var right : float = 0.75; //determines the default view of the camera when not zoomed in
var smooth : float = 17; //smooth determines speed of transition between zoomed in and default state
var orbitOTS : MouseOrbitOTS;
orbitOTS = gameObject.GetComponent( MouseOrbitOTS );

private var zoomedIn = false; //boolean that determines whether we are in zoomed in state or not

function Update () {
if(Input.GetButtonDown("Switch Shoulders")){ //This function toggles zoom capabilities with the Z key. If it's zoomed in, it will zoom out
zoomedIn = !zoomedIn;

}

if(zoomedIn == true){ //If "zoomedIn" is true, then it will not zoom in, but if it's false (not zoomed in) then it will zoom in.
orbitOTS.xOffset = Mathf.Lerp(orbitOTS.xOffset,left,Time.deltaTime*smooth);
}

else{
orbitOTS.xOffset = Mathf.Lerp(orbitOTS.xOffset,right,Time.deltaTime*smooth);

}

}

How would I change it to rotate a euler angle? thanks!
