Re: Consistent Contextual Menu in NSTableview

I would probably override -menuForEvent: instead of -rightMouseDown: .

Leopard also has a bit nicer contextual menu handing for table/outline 
views: If you right-click a row that's not currently selected it 
highlights just an outline and doesn't change the selection (you can 
use -clickedRow to get that row from within your action method(s)).
