At first I wasn't sure how I was program the 'view angle' adjustment. To be honest I'm still not sure what I am going to do with it. However with the new keyboard cables soldered in place I found that I didn't have space for full rotation of the potentiometer. I ended up removing half of the thumb wheel to get it to fit. This presented me with a thumbwheel that only slightly moves up and down. The connector acts as a stop when everything is connected. I think this is serendipitous and will probably turn into something cool.
