Is the problem that Emacs can not see <S-tab> on all systems?
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 <TAB> 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', <tab>, <S-tab>, 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.
