                            3)Select what key you want to be used as the cashout hotkey
                            4)Make a bet. As soon as the game starts, press your selected key to cashout.

Note: It is an early version. I can add other keys to the list if requested and improve the whole UI of it.

All the codes there for anyone to look at and confirm the legitimacy of the code.
