When running a vim instance in gnu screen hitting shift enter in insert mode adds an 'M' and then a newline, rather than just a newline.
Does anybody know what the problem might be, or where to look?
Relevant system info:
Ubuntu 8.04.1
Screen version 4.00.03 (FAU) 23-Oct-06
VIM - Vi IMproved 7.1 (2007 May 12, compiled Jan 31 2008 12:20:21) Included patches: 1-138
Konsole 1.6.6 (Using KDE 3.5.10)
Thanks to the comments. When checking the value of $TERM I noticed that it was xterm (as expected), but within screen $TERM was set to screen-bce. Setting TERM=xterm after launching screen resolves this issue.
Adding the following to ~/.screenrc solved the problem without having to do anything manually:
term xterm

Missing info from your question:
- Where do you run screen and see this issue? Some terminal app (KTerminal, Gnome terminal, virtual console etc) or remote session (eg putty, ssh from another computer)
- do a “echo $TERM” and tell us its output
- do a “cat -v”, press Shift-Enter, then Enter, then Ctrl-D and then tell us what is output.

First, you could fix your $TERM for within konsole. Install "ncurses-term" and configure konsole to set $TERM=konsole-256color. Then configure screen with "term screen-256color". Or 'konsole' and 'screen', respectively, if that's your preference. Konsole and screen are not xterm and doesn't support everything xterm does, so using incorrect $TERM can lead to bad things.
