I just got the Samsung D8000 LED - a couple of new codes are there.

#37 and #39 - AD/Subtitle (same as Closed Captioning which is #37)
#44 - Teletext
#63 - e-Manual
#100 - Social TV/Smart TV Log In
#115 - Search
the New Smart Hub service works on numbers 121, 140 and 147.

Don't have USB device that I can check those on but the are quite a few "Not Available" responses coming up so will need time to figure what they might be.

The qwerty keyboard remote included is bluetooth.
