Can you use a key press to change the Video playing on a Plane

I have a Plane with a movie texture which loops and then on different key presses I need various other videos to play on the same Plane, continuously switching from one to another with each key press. After searching the Answers I can't see if this can be done and I am very new to scripting. So my question is can I do this by getting the MovieTexture to play a variable changed by the key press and if so what scripting can I use? Thankyou.

My simple code so far is:

using UnityEngine; using System.Collections;

[RequireComponent (typeof (AudioSource))]

public class Video : MonoBehaviour {

 public MovieTexture movie;

 // Use this for initialization
 void Start () 
 {
     ((MovieTexture)GetComponent<Renderer> ().material.mainTexture).Play ();
     movie.loop = true;
 }
 
 // Update is called once per frame
 void Update () {
 
 }

}
