Ok sorry for using the wrong forum. I only thought about the virtual keyboard in terms of typing, that should work just fine for what I need.

Hi there, I'm playing some of the Humungous Games which don't use the global save system, but instead require pressing S to save and L to load. I'd like to play these on the Switch using only the controller inputs, however I have been unable to find a way to bind inputs to a key like S or L.
