It is not true. I have setup my console (kernel and xterm) Emacs' frames
to work almost identical to the X Window ones. Let's attack the kernel
console issue. The trick is to use kernel keymaps. Here is how it
works for the specific problem being discussed (the <backtab>
detection):
1. Discover what is your Tab key code using the command line program
`showkey'. Mine is 15; so, let's suppose also it is yours.
2. Create a keymap that include your base keymap and maps the shifted
Tab key to some unicode character (take a look at keymaps(5) man
page). Let's suppose that your current keymap is the US one
(/lib/kbd/keymaps/i386/qwerty/us.map.gz) and you want to map to the
U+010E character. Thus, your keymap will be like this:
--- begin emacs.map ---
include "/lib/kbd/keymaps/i386/qwerty/us.map.gz"
shift keycode 15 = U+010E # <backtab>
--- end emacs.map ---
3. Load your new keymap using the command-line program `loadkeys'. Make
that command to be invoked on system start-up (put it in some rc init
script). Now when you press <Shift>+<Tab> you should see a funny
character showing up on your console. The comment at the keymap's
second line remember us the purpose of that mapping and that we need
to configure the Emacs side. It lead us to the next step.
4. Now when you type `C-h c' followed by <Shift>+<Tab> you will realize
that Emacs can now detect your key press. The remaining procedure is
to map that unicode character to the input event we are interested
in. For this just make Emacs evaluate the following expression on
start-up (put it in .emacs, for example).
(define-key input-decode-map [?\u010E] [backtab])
And that is all. The xterm approach is similar and based on the same
principles. I hope it helps.
