I'm interested in getting P5 and I'd like to know if anyone out there uses a shuttle jog wheel controller (like the Contour AV Shuttle Pro.) I'd like the ability to use the jog wheel to control the parameter dials. It's really simple to do - all I need to know is if there's a keystroke associated w/ the parameter dials. If so, I can easily assign those keystrokes to my controller. Is there a keystroke reference FAQ, PDF, etc. out there someplace? A Quick Reference?? thanks!
