I tend to use [Next] and [Last] frequently in channel selection, as [11][Thru][Next][Next][Next] can be faster and simpler to type than "11 Thru 14." Since the 3.3.1 update, however, (at least on the Apexes that I've used), this has frequently, but not always, resulted in channel selections like "11 Thru 12 + 13." I think it's related to the speed with which the Next key is repeated.
