The problem is this, form `(elisp)Character Type': The case of a graphic character is indicated by its character code; for example, ASCII distinguishes between the characters `a' and `A'. But ASCII has no way to represent whether a control character is upper case or lower case. Emacs uses the 2**25 bit to indicate that the shift key was used in typing a control character. This distinction is possible only when you use X terminals or other special terminals; ordinary terminals do not report the distinction to the computer in any way. and, from `(emacs)Named ASCII Chars': With an ordinary ASCII terminal, there is no way to distinguish between and `C-i' (and likewise for other such pairs), because the terminal sends the same character in both cases. So, from the console and from `emacs -nw', , , C-i and S-C-i are indistinguishable. `emacs -nw' is important to people with a slow connection, because just emacs without `-nw' over a slow connection is just way to slow to be usable. Sincerely, Luc.
