Some keys are not giving the expected result when pressed

[Christian Andersson]

Hi!

I have a se (Swedish) keyboard layout and some of the keys doesnt work with my 
screen configuration. And i dont know how to solve the problem either.

When i press lshift+rarrow i only get some output data instead of moving the 
cursor (in mcedit) for example.

Keyboard combination | output to console
lshift+rarrow = 1;2C
alt + rarrow = 1;3C
ctrl + rarrow = 1;5C
lshift + end = 1;2F
And so on... 

The "regular" keys work as they should its "just" the special ones that are 
acting erroneously.

Setup:
XTerm(223)
zsh 4.3.2 (i686-pc-linux-gnu) (The result is the same in bash)
Screen version 4.00.03 (FAU) 23-Oct-06

My .sreenrc
===============================

# No startup msg
startup_message off

# Detatches on close instead of kill.
autodetach on

# I like a large scrollback
defscrollback 10000

# Run everything in UTF-8.
defutf8 on

#tabs at the bottom row
hardstatus on
hardstatus alwayslastline
hardstatus string "%{.bW}%-w%{.rW}%n %t%{-}%+w %=%{..G} %H %{..Y}   
[%Y-%m-%d]   %c "


# Define the shell to use
shell zsh

# No anoying bell sound
vbell off

#start with four screens and give them names
screen -t alpha 1
screen -t beta  2
screen -t gamma 3
screen -t delta 4

Thank you in advance, Christian
