One could argue Shift-Letter should be allowed for all other lowercase letters, while using the 42S-standard method when needing lowercase "g" and "h", but that could be confusing.

Actually, ASTO and ARCL are on the unshifted STO and RCL keys. This creates a conundrum because the % character is entered as shift-RCL (%). There are other keys used by the unshifted alpha keyboard. PI is entered as shift-RDN. Another special case is the small capital E used for the exponent in numbers. This is entered as the unshifted EEX key. Numbers, period and the /, *, - and + operators are all on their corresponding unshifted keys in alpha mode.

This is important because there is no way to enter these characters using the the ALPHA menus. Most of these conflicts can be resolved by abandoning shift-<character> to enter lowercase letters, and instead mapping the original unshifted value to require it be prefixed with the shift key--very much like it is done on the 41c. The problematic case is the % character. Also keep in mind that shift-SHOW is ASHOW in alpha mode.
