console vim in screen session: remap Ctrl-Shift-Left, Ctrl-Shift-Right to not delete lines

Question

I have my gvim setup so that I can select word-wise with Ctrl-Shift-Right, Ctrl-Shift-Left etc. (yes, I know it's a bad habit, but it works for me..).

Unfortunately, these key combinations delete text when used in console vim inside a screen session. I believe this is because the two key combinations produce the codes Esc[1;6D and Esc[1;6C on the terminal, which are interpreted as "delete next 6 lines" or "change next lines", respectively.

Is there some way to stop screen or console vim from interpreting these key combinations?

UPDATE: Content of my .screenrc:

sessionname daku
startup_message off
hardstatus on
hardstatus alwayslastline
hardstatus string "%{.bW}%-w%{.rW}%n %t%{-}%+w %=%{..G} %H %{..Y} %m/%d %C%a "

Clearly Vim doesn't have a binding for the key sequence ␛[1;6D but has one for some other key sequence that begins with ␛[1, probably ␛[1~ (usually sent by the Home key). Add remappings to your .vimrc to declare that ␛[1;6D is really Ctrl+Shift+Left and so on. I think the following should do the trick:

noremap <ESC>[1;6D <C-S-Left>
noremap! <ESC>[1;6D <C-S-Left>
noremap <ESC>[1;6C <C-S-Right>
noremap! <ESC>[1;6C <C-S-Right>

Here's what I have in my .vimrc:

function Allmap(mapping)
  execute 'map' a:mapping
  execute 'map!' a:mapping
endfunction
function Allnoremap(mapping)
  execute 'noremap' a:mapping
  execute 'noremap!' a:mapping
endfunction
call Allmap('<ESC>[6D <C-S-Left>')
call Allmap('<ESC>[6C <C-S-Right>')
call Allnoremap('<C-S-Left> <C-Left>')
call Allnoremap('<C-S-Right> <C-Right>')

This is what is in my .vimrc now:

if ! has("gui_running")
  noremap  <ESC>[1;6D <C-S-Left>
  inoremap <ESC>[1;6D <C-S-Left>
  noremap  <ESC>[1;6C <C-S-Right>
  inoremap <ESC>[1;6C <C-S-Right>
endif

Move the binding from ~/.vimrc into ~/.gvimrc.
