Context menus are menus displayed when you right click on some object of the user interface. (or alternatively when pressing the Windows' context menu Keyboard button while the object has focus). Context menus provide access to a list of actions available for the element that is currently in focus.
Context menu might adapt to the status of the object for which it is displayed, i.e. some elements might be disabled or invisible.
