Use the arrow keys to Sketch. Press the space bar to erase it all. When you press the Q key the pen gets bigger and when you press the W key it gets smaller. If you click the cursor somewhere then the pen moves to the place you clicked. If you press the R key your pen gets CURLY and if you press the E key it goes back to normal. If you press the T key you'll get to draw with more then one pen. Also if you click the green flag while holding shift it'll go into turbo mode and go CRAZY!
