I just managed to set up a mini Bluetooth keyboard, along with my regular USB keyboard. I want to be able to press a single button on my Bluetooth keyboard and have it control various multimedia functions - press "q" to start playing music, just as a random idea.
However, the obvious problem with that is that if I map them the normal way, then it interferes with my regular keyboard, and so I have to figure out a way to take inputs that might use the same keycode from two separate keyboards and use them for completely different purposes.
Is this even possible? I know that Linux can differentiate between different keyboards, but I don't know if it can go to this extent.
