The escape button is used to get out of some programs and to get out of games quickly and effectively. Sometimes if you press the escape button in a game, it will direct you to the main menu, and not out of the game. The escape button is labelled with a "Esc" and is located at the top left-hand corner of your computer keyboard. Hope I helped! ^^
