Responder objects can implement the methods of this protocol to handle standard editing-related actions. For example, a UIMenuController object reports editing actions using these methods. The menu controller then asks UIKit to search the responder chain for an object that implements the appropriate method, calling the method on the first object that implements it.
A custom item in the editing menu managed by the menu controller.
