Hi Randy,
sorry for the delayed answer...
I tried it today - I started the Flirc setup program, clicked on erase and pressed the select button on the harmony. The setup program told me - erased!
After that I programmed the enter button from the "Full Keyboard" layout as you suggested. Then I run to the TV to test it all and ..... same as before!
:-( ... I can navigate in the FireTV Menue as I can do it with the original remote. But when I try to use the Select button in SPMC it doesn't work. The original remote works like it should :-(
Any further hints ? ;-)
best regards
Holger
