It is definitely annoying. The corresponding getkey codes (ASM, not Axe or BASIC) are in the include file! I mean, it couldn't be that hard to expand the mode menu by one item, would it? They probably have a slight reason for doing it: lowercase letters are two bytes each. (Why they can't be one-byte tokens, I don't know. Silly TI, there are probably 26 rarely used math functions that people would be okay with becoming two-byte tokens.) Of course, the two-bytes thing is TI's fault anyway.
