Bug. User keyboard ineffectice on certain keys

[towe]

I had found that menu, but it's far from complete.

I used KA for the uppercase greek letter, but even then it didn't seem to work.
The user keyboard should really overwrite any button, regardless of function.

edit: Is there any logical reason behind why some of the extra selection tables are marked with keys for each choice (such as Shift+6) and some are not? That really downgrades efficiency.
Also, there should be a way to change between the different menus Math, CAS and App via keypress and not touchscreen.

edit2:
The a b/c key does work as intended for Alpha and Shift+Alpha variants. Normal and Shift produce the original button's result.
