I just finished a self-install of a Hopper 3 and three Joey's (two Joey 3's and one Joey 4K). Other than spending over an hour on the phone with Dish because they kept insisting on requiring a site visit, it went well. One thing that came out of the phone call was that there appears to be many different "special" key combinations available on the 54.0 remote that are not published anywhere (at least that I can find). An example is performing a check switch by pressing the skip back button, followed by recall, followed by the skip back button again. How many other combinations exist like this that aren't in any of the manuals? Has anyone made a list?
