Recently, I noticed that the Wacom Expresskey Remote I've been using with my Miix 700 for KB shortcuts without a KB is seemingly causing pen lag. My thinking is that the Wacom Tablet driver which the Expresskey Remote requires, is messing with the built in MS driver. Can't prove it 100%, but after a OS refresh, the lag is gone so... Anyways, I didn't want to do a software on screen key mapping solution since I hate UI clutter when I draw, plus I wanted something far more tactile. So I came across AntiMicro. https://github.com/AntiMicro/antimicro/releases It's a freeware app designed to map keyboard keys on to gaming controllers. It's very clean and efficient. Doesn't do macros, but you can get around that with button combos. Also recognizes BT controllers. I've ordered one of those phone VR half controllers with BT to travel around with. In the meantime, here is a video with XBox One controller.
