The color keys have already been mapped within the buzztv app. Consequently, when you launch the buzztv app and press the info button while watching TV, the bottom of the screen will display the specific functions of each key. To add the app to your favorites from the Home Screen, please press and hold the ok button for a few seconds. Because the remote control lacks a dedicated button for live TV, I have added the buzztv app to my favorites so that a single press of the star button provides immediate access to live TV. This process is quite intuitive.
