Shortcut to set anchors at corners?

Bit of an old thread but i have added Stretch To Parent too (as found i was doing this often) - and contains a shortcut to basically resetting the object to stretch to parent.

         [MenuItem("uGUI/Stretch To Parent %,")]
         static void StretchToParent()
         {
             foreach (Transform transform in Selection.transforms)
             {
                 RectTransform t = transform as RectTransform;
 
                 if (t == null) return;
 
                 t.anchorMin = new Vector2(0, 0);
                 t.anchorMax = new Vector2(1, 1);
                 t.offsetMin = t.offsetMax = new Vector2(0, 0);
             }
         }

Gwoms answer is great. I created an editor script out of it that also has a default shortcut of Shift+Q.

 using UnityEditor;
 using UnityEngine;
 
 public class EditorStretchToParent : Editor
 {
     [MenuItem("uGUI/Stretch To Parent #q")]
     static void StretchToParent()
     {
         foreach (Transform transform in Selection.transforms)
         {
             RectTransform t = transform as RectTransform;
 
             if (t == null) return;
 
             t.anchorMin = new Vector2(0, 0);
             t.anchorMax = new Vector2(1, 1);
             t.offsetMin = t.offsetMax = new Vector2(0, 0);
         }
     }
 }

You can change the default shortcut by changing the "'#q" in the MenuItem string.
