I found several questions about this, but I didn't find a working answer.

I'm using putty (0.63) to login to my ubuntu 14.04 vps.
In tmux I would like to use ctrl-left and ctrl-right to switch tmux windows.

Here are the tmux settings I'm using:

bind -n C-Right next-window
bind -n C-Left previous-window
set-option -g default-terminal "xterm-265color"
set-option -gw xterm-keys on

The terminal type string in putty is set to "xterm-256color"

When I login to the vps without starting tmux I have these keycodes:

left: ^[[D
right: ^[[C
ctrl-left: ^[OD
ctrl-right: ^[OC

After starting tmux ctrl-left has the same code as left and ctrl-right has the same code as right.

I tried different settings in putty, but I always get the same codes.

Do I need to make changes in terminfo/inputrc/...? How do I do that?

Can I solve this with "set -g terminal-overrides" in tmux ? Where can I find a list of codes or a detailed explanation?

Any idea how to get this working?

It seems I just had to add this to .tmux.conf:

set -g terminal-overrides "xterm*:kLFT5=\eOD:kRIT5=\eOC:kUP5=\eOA:kDN5=\eOB:smkx@:rmkx@"

I tried that before, but there already was a different "set -g terminal-overrides" in the config with other settings. After removing that everything worked.

I found the solution here: https://bbs.archlinux.org/viewtopic.php?id=129912

Update: Here my complete tmux config after some more changes:

bind -n C-Right next-window
bind -n C-Left previous-window
set-option -g default-terminal "screen"
set -g terminal-overrides "xterm*:kLFT5=\eOD:kRIT5=\eOC:kUP5=\eOA:kDN5=\eOB:smkx@:rmkx@:XT:Ms=\E]52;%p1%s;%p2%s\007:Cc=\E]12;%p1%s\007:Cr=\E]112\007:Cs=\E[%p1%d q:Csr=\E[2 q,screen*:XT,*256col*:colors=256"
