You can use a mini bluetooth game controller as an iPad hotkey gadget

Check out this video of artist TerraTerrific using the miniature 8bitdo Zero game controller as a bluetooth hotkey gadget on the iPad, executing commands like 'undo' and switching tools without having to interrupt the painting hand.

I bought one of those 8bitdo zero controllers to use for clip studio shortcuts on the iPad and uh...I dig it. pic.twitter.com/mBhjUjJq9g
