Regarding button scripts, each DefineButton() record has one or more events defined as scripts with the same number as the button itself. They are usually on(release) , on(press), on(keyPress "2") and so on. Such script is executed when mouse is pressed, released respectively, when over button area. Similar with keyboard key press.
