Quick Object Instantiator within Unity Editor - Help!

Hi there,

I’m trying to make a quick-object placer script that allows me to use keyboard buttons 1-2-3…0 to instantiate items on cursor position. The script is NOT to be used in playmode, but to be used in editor to help build levels faster.

I can do it via GUILayout.Button, but I’m unable to use key bindings via my script in editor.
The script resembles something like this;


 #if UNITY_EDITOR
    [CustomEditor(typeof(QuickBuildTool))]
    class BuildEditor : Editor
    {
       public override void OnInspectorGUI()
        {

               if (GUILayout.Button("Instantiate Asset"))
            {                
GameObject newObj = PrefabUtility.InstantiatePrefab(targ.kitchenItems[0]) as GameObject;
//I want to press "1" to insantiate kitchenItems[0] instead of doing it by inspector buttons.
}
}

Can you please advise me on how to proceed?
