Provides a registry for commands that you’d like to appear in the context menu.
An instance of this class is always available as the atom.contextMenu
global.
'atom-workspace': [{label: 'Help', command: 'application:open-documentation'}]
'atom-text-editor': [{
  label: 'History',
  submenu: [
    {label: 'Undo', command:'core:undo'}
    {label: 'Redo', command:'core:redo'}
  ]
}]
In your package’s menu .cson file you need to specify it under a
context-menu key:
'context-menu':
  'atom-workspace': [{label: 'Help', command: 'application:open-documentation'}]

The format for use in ::add is the same minus the context-menu key. See
