Discussion
This method is invoked every time the user clicks the right mouse button, or control-clicks, on an element to reveal a contextual menu. The receiver typically returns a modified copy of the default menu items dictionary, adding and removing menu items as appropriate for this type of element. You can use this mechanism to remove items that are not appropriate for a particular environment or task, such as saving files to the desktop in a web kiosk. You do not need to set the actions and targets of the default items.
