[Orgmode] GNU Screen and arrow keys

[lore]

My emacs lives inside a GNU Screen session.

When I say M-<left> to promote current heading I get '3C'.

googlin' around I found:

Everything works properly using emacs outside screen.


Is out there a workaround for this? I need screen :)

Thank you in advance for your help.


* My setup
  - gnome-terminal            2.18.4
  - GNU Screen                4.00.03
  - emacs                     23.0.50.1
  - org.el                    5.19a
