How to use a remote presenter device to run custom programs?

Question

I have a remote presenter device that connects to my laptop using a usb dongle. It works perfectly for switching slides with Ubuntu's LibreOffice Impress (powerpoint). Is there a way to scan for these commands from my own c/c++ code and do what I like with them?

You could check if it's sending keyboard events with xev -event keyboard. If so, you could maybe find some helpful info at How can I change what keys on my keyboard do? — wjandrea, Jul 24 '18 at 22:44
