toggle a checkbox in a property

[Uwe Brauer]

Hi 

Look at this example

* Test
  :PROPERTIES:
  :ID:       46b9eb11-e258-4dc9-bf56-3c2112cf6b0a
  :Received: [X]
  :END:

Using `org-shiftright'

I can obtain 

* Test
  :PROPERTIES:
  :ID:       46b9eb11-e258-4dc9-bf56-3c2112cf6b0a
  :Received: [ ]
  :END:

But how can I obtain 

* Test
  :PROPERTIES:
  :ID:       46b9eb11-e258-4dc9-bf56-3c2112cf6b0a
  :Received: [-]
  :END:

org-toggle-checkbox does not work for these sort of checkboxes.
