Except for the FAVORITES mode, I have remapped my channel keys to perform the ChannelUp and ChannelDown functions of my Satellite Receiver:

(1)It's much quicker than having the Harmony execute the commands for EACH NUMBER (then ENTER);
(2)By editing what channels are ACTIVE on my Satellite Receiver (nothing to do with the Harmony Remote) and removing those channels which I don't watch at all, the ChannelUp and ChannelDown functions become even more efficient;
(3)In the FAVORITES mode for the Harmony, the Harmony will still execute the numeric sequence if I need it to go to a SPECIFIC CHANNEL that I selected via the wheel.

This makes surfing much more efficient for me.
