A video is one of the things I've been meaning to do but just haven't gotten around to making it. Definitely going to wait until I finish assembling the version with the control and alt. keys.
The only place I've found to buy a shuttle/jog control like this is to get it from Contour, I've been using the Xpress device as the donor. If I ever get the time, I'll build an entirely new jog/shuttle control.
Updated the page with the new button configuration, you might need to refresh your cache to see the new image. I have a much higher resolution image if you click on the small version. transportcontrols.com/
