Has anyone managed to remap the buttons on the surface pro 3 pen? To be specific, I mean the left click button and the erase button. Unfortunatly the application that I use daily ( unity3D) does not register any pen interaction. I'm somewhat familiar with autohotkey, I'm currenly using keyboard keys to emulate mouse buttons (yes, it's horrible). I don't know how to retrieve the pen button ID's, so I can't map any actions to those. Thanks.
