When setting hotkeys, is it possible to go back to the default key (like a key combination to reset). I have set a button by mistake and now I can’t get rid of it. If not, is it possible to wipe the hotkeys keys so that they can be setup again.

Tip
To unbind (effectively, disable) a hotkey, press Del on your keyboard or the Y button (the left one of the 4 buttons) on the RetroPad. To reset a hotkey to its default, press Space on your keyboard or the Start button on the RetroPad.
Thank you so much. The “Y” button (or 4 on mine) was one of the keys that had been assigned. Thanks for the link, will come in useful. In the end, I searched though RetroArch.cfg and found the setting there but this will be a lot easier.
