I don't see the point of this feature; Control-Click is quite standardized across OS X applications (and works quite happily in Pd as well). Considering that anyone using Pd probably has a 2 button mouse (or has learned to control click), this is basically just a huge PITA.
The example that finally brought me here was changing arguments to 64 instances of an abstraction in a patch I'm working on: one click selects the entire text of an object box, and another should place the cursor - oh, that's unless you click too fast, in which case you get a @#$% contextual menu. Ok, I'm going to go have a beer : ).
I'd love to learn that this was a simple mistake on my part!
Thanks, Luke
