inputManager - Finding All Keys Used

Is there any way in jMonkey to get all the keys that I am using in inputManager? and by that I mean keyboard keys and mouse buttons?

I am trying to allow users to setup their own keys - however - only on the buttons that I am not using in my main application (won’t let them override these buttons) - thus, I wanted some quick search on this list of buttons to make sure it does not contain the button the user is trying to use.

I’d suggest approaching it from a different angle.

Make all buttons configurable including your “main” ones and have a unified config screen for them.

Could you please explain more?

edit: and by that I meantspecifically

and have a unified config screen for them
