docstring: Select / deselect list item in a control having only one item.
  
          If the control has multiple list items, ItemCountError is raised.
  
          This is just a convenience method, so you don't need to know the item's
          name -- the item name in these single-item controls is usually
          something meaningless like "1" or "on".
  
          For example, if a checkbox has a single item named "on", the following
          two calls are equivalent:
  
          control.toggle("on")
          control.toggle_single()
