Global tools vs. contextual tools

Some custom tools are global and others are contextual:

• A global tool affects any type of GameObjectThe fundamental object in Unity scenes, which can represent characters, props, scenery, cameras, waypoints, and more. A GameObject’s functionality is defined by the Components attached to it. More info
  See in Glossary, and is always available no matter what type of GameObject you select. For example, a transform tool could be accessible all the time because it works with any GameObject.

• A contextual custom tool only affects a specific type of GameObject, and is only available when you select GameObjects of that type. For example, a custom manipulator for lights should only be accessible when you select a light.
