Place your index finger on the track pad on your computer, then drag your index finger to the spot on the track pad that allows the mouse to hover over the image of the green flag on the screen. Then lift your index finger up from the track pad and push it back down hard, but not too hard, just enough that you will hear a small click. Then lift your finger back up and use the muscles in your eyes to point them towards the screen letting them continually send signals to your brain until the project has come to an end. But in other words, click the green flag and enjoy.
