The terminal generates the keycodes (at least that's what I think). So 
if the terminal generates the same keycodes for shifted and un-shifted 
keys there is no way for the standard tools (readline in bash, zle in 
zsh) to distinguish these and to assign differenct actions to them.

The question is why you do have different actions for those in Cmd 
(which uses the same Windows terminal). Maybe because Cmd does not use 
the same "keycode" mechanism as the Unix terminal/shells. But that's all 
more or less guessing.
