Parameters
----------
event : gtk.gdk.Event
GTK mouse click event.
shape : str
Electrode shape identifier (e.g., `""electrode028""`).
Returns
-------
gtk.Menu
Context menu.
.. versionchanged:: 0.13
- Deprecate hard-coded commands (e.g., clear electrodes, clear
routes).
- Add anonymous global commands section at head of menu (i.e.,
commands not specific to an electrode or route).
- Add ""Electrode"" and ""Route(s)"" sub-menus.
