Computer software allowing enhanced control of the playout of audio/video works on a computer system. In various embodiments, the software allows key events from dedicated audio/video keys, whether part of a full sized keyboard or on a hand-held remote, to control the actions of an audio/video playout program running within a browser environment without requiring the user to direct the key event focus of the operating system to the audio/video playout program. In one embodiment, software associated with the browser window forwards to the audio/video playout program any key events received from audio/video keys.
