How To Get The A Code For The Button? If You Gave Me A Code I Would Make A Chatting Thing

I don't understand your question. Please elaborate. Also Please Stop Talking Like This It Hurts People's Eyes

IF BUTTON() AND #A will detect whenver someone is holding the A button.

IF BUTTON(2)==#A is a little more specific than BUTTON() AND #A because you can specify how you want to handle the button press (continuously run code if it is held down or only activate once when it is pressed or unpressed)
