It can enhance your mouse and keyboard with customizable macros, sniper modes, key repeat rates and repeat delay, turning your boring old keyboard and mouse into lethal weapons. Key Master may be prohibited by some games. We suggest disabling Key Master if it violates the game's end user license agreement.
