Extra mapable buttons

[BlueCheeseMario]

I want to use the extra buttons on my controller and keyboard, but I'm not sure how to do it. The base buttons are not enough for the quick power-up select I was wanting.

There is a LunaLua event that triggers whenever a keyboard key is pressed. Same goes for controller buttons. Then you just need to let the player know somehow, which button does what or if you want to go more advanced make a custom menu where the player can remap all inputs to his own liking.
