Re: (kbd "S-TAB") doesn't work

[Richard Stallman]

     (define-key map (kbd "S-TAB") 'nero-move-to-previous-link)

    should work, i.e., it should do the same thing as

     (define-key map [(shift tab)] 'nero-move-to-previous-link)

(shift tab) is equivalent to the symbol S-tab, a shifted keyboard key.
(kbd "S-TAB") is equivalent to the ASCII TAB character with the shift
modifier.  They are indeed not the same.

It is certainly unfortunate and potentially confusing that they are
not the same.  But which one should we change?  Is either of them
"wrong" in some sense, and in need of being changed?
