KeyBoard Input for Back to scene after prefab editing

EDIT: Ignore the example below as we have added builtin shortcuts in 2018.3 after this message. Customize it under: Preferences -> Keys -> Stage.
Stage/Enter Prefab Mode
Stage/Go Back


We have not settled on built-in keyboard shortcuts yet. Until then add this script to an Editor folder.

Code (CSharp):

1. using UnityEngine;
2. using UnityEditor;
3. using UnityEditor.SceneManagement;
4.  
5. public static class StageShortcuts
6. {
7.     [MenuItem("GameObject/Navigate Back %w", false, 10000)]
8.     static void NavigateBack()
9.     {
10.         StageUtility.GoBackToPreviousStage();
11.     }
12.  
13.     [MenuItem("GameObject/Open Selected Prefab %e", true)]
14.     static bool ValidateOpenSelectedPrefab()
15.     {
16.         return !string.IsNullOrEmpty(GetPrefabAssetPath(Selection.activeGameObject));
17.     }
18.  
19.     [MenuItem("GameObject/Open Selected Prefab %e", false, 10000)]
20.     static void OpenSelectedPrefab()
21.     {
22.         var activeGameObject = Selection.activeGameObject;
23.         var prefabPath = GetPrefabAssetPath(activeGameObject);
24.         if (!string.IsNullOrEmpty(prefabPath))
25.         {
26.             var assetObject = AssetDatabase.LoadAssetAtPath<GameObject>(prefabPath);
27.             AssetDatabase.OpenAsset(assetObject, EditorUtility.IsPersistent(activeGameObject) ? -1 : activeGameObject.GetInstanceID());
28.         }
29.     }
30.  
31.     static string GetPrefabAssetPath(GameObject gameObject)
32.     {
33.         if (gameObject != null && PrefabUtility.IsPartOfAnyPrefab(gameObject))
34.         {
35.             return PrefabUtility.GetPrefabAssetPathOfNearestInstanceRoot(gameObject);
36.         }
37.  
38.         return null;
39.     }
40. }

 

FYI In 2018.3 we have added keyboard shortcuts you can customize under Preferences -> Keys -> Stage

See:
Stage/Enter Prefab Mode
Stage/Go Back

The default key for 'Enter Prefab Mode' is [P]
