How can I used OnMouseDown like a switch button one click to move forward another to move back ?

Code (csharp):

1.  
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5.  
6. public class VideoSettings : MonoBehaviour
7. {
8.     public MeshRenderer VideoAudioCube;
9.     public float speed = 5f;
10.     public float distanceToMove;
11.  
12.     private bool keepMoving = true;
13.     private Vector3 startPos;
14.     private Vector3 endPos;
15.  
16.     private void Start()
17.     {
18.         startPos = VideoAudioCube.transform.position;
19.     }
20.  
21.     private void OnMouseDown()
22.     {
23.         if (keepMoving == true)
24.         {
25.             keepMoving = false;
26.             if (transform.GetComponentInChildren<TextMesh>().text == "Video")
27.             {
28.                 StartCoroutine(MoveVideo());
29.             }
30.         }
31.     }
32.  
33.     private IEnumerator MoveVideo()
34.     {
35.         endPos = VideoAudioCube.transform.position + Vector3.right * distanceToMove;
36.  
37.         VideoAudioCube.enabled = true;
38.  
39.         while (VideoAudioCube.transform.position != endPos)
40.         {
41.             VideoAudioCube.transform.position =
42.                 Vector3.MoveTowards(VideoAudioCube.transform.position, endPos, Time.deltaTime * speed);
43.             yield return null;
44.         }
45.     }
46. }
47.  

When I click with the mouse on the object the object move one to some distance.
Now I want to do that another click will move the object back to it's startPos so the OnMouseDown will be like a switch button. Each click will move it to the other direction endPos and startPos.

 

Just keep track of a bool that is back/forth essentially, and when you click, decide which way to move, then invert the bool from true back to false, and vice versa.
