Hello Old Bruce. The Intuos BT M graphics tablet is just a smaller version of their pro model without some of the features. See attached image below. The BT means it is Bluetooth enabled and the M refers to size medium. I actually discovered that I had the brush and pen controller mode set to none in the affinity apps. After I switched that to automatic, the pen pressure works great for changing the size and stroke for the brush and pen tools, I believe. However, I would still appreciate a tutorial on how to customize some of the more common functions to the tablet so that I don't have to constantly switch between the keyboard, trackpad, and graphics tablet.
