I uses screen under rxvt-unicode, in my .vimrc, I map the Shift-Up key

As soon as I'm under screen it doesn't work anymore.
Found the reason why my keymapping doesn't work with vim under screen.
I guess vim interprets the escape sequence differently according to
the TERM's environment variable and in my case it's "screen".
If I do export TERM=rxvt under screen then the key binding is ok with vim
What makes vim reacting differently between TERM=rxvt and TERM=screen ?
Is there a way to make things work properly or should I export
TERM=rxvt each time I run screen ?
Different terminals may represent the same key differently. If using
:noremap <S-Up> zc
(with <S-Up>, not <Esc>[a ) doesn't work, then it could that mean your termcap
is broken, or that your $TERM is not properly set.
If _all_ keys are recognised properly if you set $TERM to 'rxvt' under screen
then a possibility would be
if &term == "screen"
set term=rxvt
endif
unless there are other consoles, with other termcaps, which can be used
through screen, in which case you must make sure that screen does not set
$TERM to 'screen' regardless of what actual console it runs in, but instead
leaves that variable set at whatever it was set before.
