The manual that came with the G series is lacking in description of how to program the color keys and the star key.  Anyone know how to do this?

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.

Programmable shortcut keys (not color keys) will prompt you for choosing what you want them to be mapped to the first time you try to use them.

If you want to remap them later, you can Just hold the button down for about 3 or 4 seconds and once you release it will prompt you again to reassign it to a different app/action. 

Even the FreeTV button can be mapped to what you want.
