Guess you don'y know what AutoIt is. It doesn't use the mouse, it can submit and change forms, load web pages, etc. Say you wanted to login into Facebook, First you would tell it to load Facebook, then you'll need to find the form for the login, then add your login info into the script, and click play. Opens am internet explore web browser then, loads Facebook, and then logs you in. So you can do other stuff while the script is running and not have your mouse taken up, sort of like smart.
