use your mouse to draw a picture click to stamp a smily face you start out with a pencil. you can change it with "z, x, c, v, b, n, and m." to change back to pencil, press "s." to erase, press "a." change the pen size with the right and left arrow keys. i'm going to let you figure out what space does. (don't worry, it's not bad! strange, though.)
