This looks like the answer :


,----[ (info "(elisp)Function Keys") ]
|      In ASCII, `C-i' and <TAB> are the same character.  If the terminal
|      can distinguish between them, Emacs conveys the distinction to
|      Lisp programs by representing the former as the integer 9, and the
|      latter as the symbol `tab'.
|
|      Most of the time, it's not useful to distinguish the two.  So
|      normally `function-key-map' (*note Translation Keymaps::) is set
|      up to map `tab' into 9.  Thus, a key binding for character code 9
|      (the character `C-i') also applies to `tab'.  Likewise for the
|      other symbols in this group.  The function `read-char' likewise
|      converts these events into characters.
