I want to debug my keyboard and figure out what would happen after I pressed the key. Is there any debug tools or solutions to track the keyboard events or handlers? I searched the Internet and only found one useful answer (Debug/fix a key autorepeat issue?)

For example, I press a Volume control key, how does it trigger an event and control the driver to turn up/down  ? And how to track the control flow of it?

I'm using arch Linux on my laptop, so any solution for Linux is welcome. Thanks~
