Keyboard shortcut for toggling todo iscompleted status

I'm looking for the keyboard shortcut to mark a toDo as completed or unCompleted (isCompleted:0 or 1). Currently the only way seems to be to manually click the toDo checkbox in the notes lists

I've surfed through the forums but am amazed I can't find anyone else asking this question: Is there something I'm missing, or has anyone found a work around/plugin?
