Eat it.

I don’t think apple would allow these types of stuff.

hm

I’m not 100% sure on that

I do believe you can catch the event and then once you do that you can do whatever you want

aka in the code

if (volume_button_up)
// jump or whatever

but idk if you can prevent the button from also doing its default behavior of manipulating the volume, so the volume will still go up/down
