vim: bind ctrl+shift+aletter

[ping]

guys:
is there a way to bind ctrl+shift+p differently that ctrl-p ?
google told me NO, since they are the same "key code".
just double check to experts here as last hope or any close workaround...

You can find out for yourself by entering insert mode and typing
Ctrl-V followed by each of the key combinations you want to try.
I tried on Linux using vim in a terminal and gvim and both key
combinations produced the same result in both cases:  ^P.  If Vim
doesn't distinguish between the key combinations in that situation,
it can't when you use them in mappings, either.  See

    :help i_CTRL-V

Gary

Please read the faq:
http://vimhelp.appspot.com/vim_faq.txt.html#faq-20.4
and possibly also Question 20.5

thanks!
so quick conclusion is:
no way for ctrl-shift-c/v(like in gnome)
fn is the only choice (but not convenient)

side-topic:
speaking of the terminalApp interception, looks xterm is the one has
less (no?) of it, means "vim friendly". isn't it?





=========================================
20.5. Why does mapping the <C-...> key not work?

The only Ctrl-printable-key chords which Vim can reliably detect
(because they
are defined in the ASCII standard) are the following:

         Ctrl-@                 0x00            NUL
         Ctrl-A to Ctrl-Z       0x01 to 0x1A
         Ctrl-a to Ctrl-z       0x01 to 0x1A
         Ctrl-[                 0x1B            ESC
         Ctrl-\                 0x1C
         Ctrl-]                 0x1D
         Ctrl-^                 0x1E
         Ctrl-_                 0x1F
         Ctrl-?                 0x7F            DEL

Most of these, however, already have a function in Vim (and some are
aliases of other keys: Ctrl-H and Bsp, Ctrl-I and Tab, Ctrl-M and Enter,
Ctrl-[ and Esc, Ctrl-? and Del).

The "safest" keys to use in Vim for the {lhs} of a mapping are the F
keys, with or without Shift: <F2> to <F12> and <S-F1> to <S-F12>. (Some
OSes, including mine, intercept Ctrl-Fn and Alt-Fn, which never reach an
application program such as vim or gvim).

You can try other combinations of Ctrl + any key, but they may either
not work everywhere (e.g. the terminal might not pass that key to Vim,
or they might have unintended side effects (e.g. mapping <C-I> means
also to map <Tab>).

That's not entirely correct. You can configure your terminal
emulator to send a different keycode for ctrl-shift-c/v if your
emulator supports it - and then map that other key in Vim
(obviously works only for terminal Vim).

For example rxvt-unicode supports remapping the input. The
following entry in .Xdefaults remaps Ctrl-Shift-c to esc x (just
an example, you could also use the F* keys or any other unused
key):

    URxvt.keysym.Control-0x43: \033x

0x43 is the keycode for upper c. Shift-c or Shift-0x63 (0x63 is
c) doesn't work!

Reload the changes:

    $ xrdb -merge ~/.Xdefaults

Then open a new urxvt window and remap the key in Vim:

    :map <esc>x ...

This should work for any key combination, use xev to get the
keycode for the desired combination. The rxvt man page has
additional information:

    $ man urxvt | less -p '  keysym.sym'

Simon
