The Last and Next keys are great for working within ranges, but something I often find lacking is a way to go to specifically the first or last object in a list. This is most common working with cuelists, wanting to get to the end or beginning of the list easily requires tricks like [Cue] 9999 [Last] or [Cue] 0.1 [Next].
My suggestion is that [Shift]&[Last] make First and [Shift]&[Next] make Final. I don’t recall there being a shift function for these keys currently?
this could also apply for other uses of [Last] & [Next].
