Fred... I don't understand that. You don't have to program anything. Just open System > Preferences > Keyboard Shortcuts, and you can easily configure your shortcuts as you please. No programming is necessary, just click which action you want to assign Super L to and press Super L to assign it.
I personally think it's annoying to have an action assigned to Super L alone, but if it should be assigned to anything, it should open the Keyboard Shortcuts configuration editors, so new users can discover that feature.
