I use Karabiner on MacOS to rebind e.g. Caps Lock to Left CMD, and Left CMD + j to Arrow Down. Sometimes Pico-8 interacts strangely with this, interpreting it as though I'm pressing CMD and Arrow Down, while Karabiners Event Viewer shows it as:
CMD pressed
CMD released
Arrow Down pressed

I understand this is tricky to solve, but I think it could be all right if I could just unbind the Cmd + Down = end of document hotkey in Pico-8. Is there a way to unbind or rebind editor hotkeys in Pico-8?
