Moving objects with keyboard shortcuts

Thanks for the tips but the Input.GetKey is not woking on my script: #if UNITY_EDITOR

 using UnityEditor;
 using UnityEngine;
 
 
 [InitializeOnLoad]
 
 class MoveGameObject {
 
     static MoveGameObject () {
         EditorApplication.update += Update;
     }
 
     static bool isCommandDown;
     static void Update () {
         //Debug.Log (Selection.activeGameObject);
         if (Input.GetKeyDown (KeyCode.A)) {
             Debug.Log ("key");
         }
         if (Input.GetKeyDown (KeyCode.LeftApple) || Input.GetKeyDown (KeyCode.RightApple)) {
             Debug.Log ("keydown");
             isCommandDown = true;
         }
         if (Input.GetKeyUp (KeyCode.LeftApple) || Input.GetKeyUp (KeyCode.RightApple)) {
             Debug.Log ("keyup");
             isCommandDown = false;
         }
         if (isCommandDown) {
             GameObject go = Selection.activeGameObject;
             Debug.Log (go);
             if (go && Input.GetKeyDown (KeyCode.RightArrow)) {
                 go.transform.position += new  Vector3 (1f, 0f, 0f);
             }
             if (go && Input.GetKeyDown (KeyCode.LeftArrow)) {
                 go.transform.position += new Vector3 (-1f, 0f, 0f);
             }
         }
     }
 }
 
 #endif

not in the IDE itself, but there are assets fro it surely

however you can do very simple piese of code whcih will basically check if there was pressed CMD and UpArrow in the same time and check for it on update

 if (Input.GetKeyDown("nameofthekey"))
         {
             nameofthekey = true;
         }
         if (Input.GetKeyUp("nameofthekey"))
         {
             nameofthekey = false;
         }
 
         if (Input.GetKeyDown("nameofthekey2"))
         {
             nameofthekey2 = true;
         }
         if (Input.GetKeyUp("nameofthekey2"))
         {
             nameofthekey2 = false;
         }
 
         if (nameofthekey && nameofthekey2)
         {
             bothkeysarepressed = true;
         }
         else
         {
             bothkeysarepressed = false;
         }
