Well, if that’s the case than I think you can still set up inputs for every key and then have them have different text strings for example:
You could set up the inputs for all your keys, and then set up print lines or print text to the input and make the text say something like (Key name) was pressed. It would take a while but it is the way that is the simplest. You could always attach an event or cast to a widget but that is a lot more time consuming and harder.
Hope that helps.
