Listen for key input from editor script

I use an editor script placed in editor folder, which listens to a key pressed.
When the key is pressed, it is supposed to trigger a function from MonoBehavior script. The issue is that the function does not get triggered at all. I am even adding EventSystem in my inspector. What is the problem here? :

Code (CSharp):

1. [CustomEditor (typeof (Switcher))]
2. public class SiwtcherEditor : Editor {
3.     void OnSceneGUI () {
4.         Switcher script = (Switcher) target;
5.         Event e = Event.current;
6.         switch (e.type) {
7.             case EventType.KeyDown:
8.                 {
9.                     if (Event.current.keyCode == (KeyCode.A)) {
10.                         Debug.Log ("A pressed");
11.  
12.                         script.SwitchHere();
13.                         e.Use ();
14.                     }
15.                     break;
16.                 }
17.         }
18.     }
19. }
20. public class Switcher : MonoBehaviour {
21.     public void SwitchHere () {
22.         Debug.Log ("GotINPUT");
23.     }
24. }

 

Is your Editor script inside Assets/Editor folder?

 

Yes, of course, Editor script is inside Assets/Editor folder.

 

its work only if you actively selected on the scene, if you select from Hierarchy/Inspector or other windows it will not run

select the object on the scene and press "A" you should see the log
