when it asks you what key you want to press, some of them don't work so you have to experiment. If you make a variable named anything and set it to "enter", and then put that variable in the "key (space) pressed?" block it reacts to pressing enter. This also works with punctuation but not other things like "tab" or "shift"
you will know that it works because when you press the key you specified, the button will press down.
