I stumbled upon this tip from a Youtube video. The Nintendo 'Joycons' can be sync'd via Bluetooth with PCs and used as a very nice 'shortcut' device for illustration applications. I wouldn't recommend going out and buying a Joycon (like I did), but if you have one, you should give it a shot and see if it makes your life easier if you use your keyboard a lot in conjunction with your tablet.

You'll need additional drivers and an app to get it working, and if you need guidance, I can lend a hand.
