Why are Assignable Switches referred to as AF1&2 in Performance and Arpeggio names?
AF = Assignable Function Switch, in full.
Agreed, Yamaha has problems, repeatedly, finding a consistent blend of readily discernible nomenclature semantics, common sense language usage, legacy terminology and marketing buzzword bingo.
Previous keyboards abbreviated these as AF in the past and there is carry-over. Also AF is shorter than A.SW which is how [ASSIGN 1] and [ASSIGN 2] are abbreviated.

Thanks @Andrew & @J. I will be able to sleep soundly tonight. 😉
