OK, I'll add that to my to-do list. At the moment I'm struggling to get Esc to behave my Meta key. This is on both my ThinkPads.You could have your window manger capture C-left/right and send two key events instead.
This seems to do what I want:-You always have to use a 'prefix' key. So tmux knows the next character is for it, not the application running in that session.
# Ctrl + arrow to switch windows
bind -n C-Left previous-window
bind -n C-Right next-window
