You can't bind arbitrary key strings at the moment and it wouldn't work
anyway because:
- The program must tell xterm to send these and tmux doesn't do this.
- emacs only accepts the keys when TERM=xterm, not when TERM=screen.
There has been some talk of supporting xterm modifyOtherKeys but so far
nobody has done it.
This diff will send the sequence to turn on modifyOtherKeys and pass
C-Enter through which should be enough for you if you can persuade emacs
to accept it inside tmux.
However I'm not going to commit it as it is, because I think we need to
a) support all the keys modifyOtherKeys affects, not just Enter b) only
send them through to the terminal inside if the application has
requested them with CSI 4;1m or CSI 4;2m and the xterm-keys option is
enabled. If you feel like picking it up that would be great otherwise
it'll have to wait til I get the time and inclination to finish it :-).
