Thank you, this does solve the problem.

In my case, it's the keyboard on my laptop, and these multimedia keys are quite common for laptop keyboards.

That refers to Android phones, right?

Such keys are fairly common on standard keyboards, or at least used to
be.  There is usually an extra "function key row" with a "volume down"
key that generates XF86AudioLowerVolume.  I have one of those keyboards
lying around.

Is there a way to support this on mobile phones without this key
breaking on machines with regular keyboards?
