This is a small editor extension for Unity for quickly and easily selecting the parent of an object. The parent object, or the root object can easily be selected with a hotkey. Also included is a component you can add to a gameobject that will automatically select its parent when you try to select it. This is useful when you for example have a hierarchy with a scene selectable object as a child, when you don't want to move this object in local space but instead always move its parent.

@Skjalg I have simply created a menu-item with a hotkey assigned, it's documented here http://unity3d.com/support/documentation/ScriptReference/MenuItem.html
