Can anyone tell me how to enlarge the minimap by pressing m creating a gentle effect as lerp function? I have done this but the effect is abrupt and orrible.could you tell me how I could use the lerp function with this code or something that will give the same effect?

using UnityEngine;
using System.Collections;

public class MinimapExpand : MonoBehaviour {

public Camera cam;

void Update () 
{
	if(Input.GetKeyDown(KeyCode.M))
	{
		if(cam.rect.x == 0.76f)
		{
			cam.rect = new Rect (0f, -0.6f, 1.0019f, 1.61f);
		}

		else if(cam.rect.x == 0f)
		{
			cam.rect = new Rect(0.76f, 0.73f, 0.22f, 0.24f);
		}
	}		 
}

}

My best guess is to give every value of the rectangle its own variable and change the size of the each value using smooth damp when M is pressed and released.
