Some keys not working under screen in vim

When using vim under screen, some keys are not working.

Namely, Pressing Alt-Left produces '3D' and Alt-Right produces '3C'

Also, pressing Up/Down when scrolling list of files in Command-T plugin produces 'A' and 'B' respectively.

When I exit the screen and run vim just under ssh session, all works fine.

Are there any settings in screen itself or terminal server/client I can tweak to fix this issue?

Solution

Modify your .screenrc section

term xterm

Or modify your .vimrc:

if match($TERM, "screen")!=-1
  set term=xterm
endif
