The Dink Network

I just started the game and I can't figure out the controls! When I go to change the controls it only says things like "button 1" but I don't know what exactly "button 1" is! I've learned easy one like ctrl is "attack" but the other I don't know them all cause I don't know the buttons. So if someone could please tell me or give me a link to what all the available buttons are that would be a big help!
Thanks.
