Input

i want to have in my game a highscore screen where the user can input there name. But i dont want to use a input box so the the only way i can see of doing it is to check for every button press. and when they press the button the value of that button is added to a string and the string is then displayed in the draw function everytime. But this would mean checking for each button press on the keyboard. but there must be a easier and shorter way. So hopefully someone might have an idea. Thanks in advance Ructions
