Newb to the forum. I searched the Harmony threads and saw a host of other issues, but nobody asked about this, which leads me to believe there is a simple answer or no good answer. Just swapped my Hr10s for Hr20s and need to program the two Harmony 680s we have. The 680 does not have a "Prev" button like most of the other Harmonys do. This wasn't an issue with the tivo because the "enter" key doubled as the "prev" button. Am I relegated to using one of the LCD soft buttons as a Prev? Or mapping another button for it like the Pic button? Without the dual tuner buffers, I think I am going to be using the Prev button a lot more with the Hr20 than I did with the HR10. PS - I am in the office right now and can't access my Harmony account to see if the solution might be more evident.
