I was going to say the same thing, or similar.

`TAB` = `C-i`.

`TAB' is not the same as `<tab>'.

(kbd "S-<tab>") => [S-tab]
(kbd "S-TAB")   => [33554441]

Yes.  IIUC, to be more exact, <backtab> takes care of two cases:
<S-tab> and <S-iso-lefttab>.

To get the effect of <backtab> for Emacs prior to 22 you had to
bind both of those keys ([S-tab] and [S-iso-lefttab]).

I'm using Ubuntu 11.10, with gnome/metacity. (on a french keyboard)

Typing S-TAB gives:
<backtab> (translated from <S-iso-lefttab>) is undefined

I'm just wrong, sorry for the noise - I overconfidently answered without 
rechecking my .emacs, I was actually doing:

(global-set-key (kbd "<backtab>") ...)

probably /because/ the more naive "S-" didn't work.

I can reproduce this on current master:

0. emacs -Q
1. (global-set-key (kbd "S-TAB") (lambda () (message "FOO")))
2. S-TAB

And see the following error: "<backtab> is undefined"

Best regards,
Stefan Kangas

You say "S-TAB", but that's not the key you pressed.  You pressed
<backtab>, a function key, whereas S-TAB is a shifted ASCII character.
Try "C-S-i" instead (which will also reveal a minor unrelated bug in
your recipe ;-).

Hmm, now I see.  This stuff always manages to confuse me.  And I guess
it also managed to confused Chong Yidong...?

Not sure if there's anything to do here, if this is as it should be.
Notabug?

Yes, I think this is just a confusing subtlety of function keys vs
ASCII keys on a modern keyboard.  The OP should have bound <backtab>,
not S-TAB.

Btw, binding <S-tab> would have also done TRT in that use case.
