@thatcomicsguy Wow, your Tecra has evolved into something impressive! I unfortunately haven;t tried to keep up with Windows Touch and Pen input api since they kept on changing it about every 2-3 months during the Windows 8-10 early days. So I won't be of much help with that and would unfortunately not have much time right now to dedicate to learning about it. The only way I know to enable/disable the touch input is to toggle the touch input device in Device Manager, but that's probably not what you want since it would take a couple of seconds to turn back on once you stop using your keyboard. The button on your Canvas is probably a much better alternative. Let me know what you think!
