resolve key conflict temporarily

[zchrissirhcz]

Issue description

I'm using C-x (control + x) as prefix, which is also the "exit key" for nano editor. I can't exit nono editor by pressing C-x or C-x C-x. I don't like to change my prefix key. How can I exit nano editor elegantly (i.e. not using kill or pkill command for nano).

To reproduce:
step1: prepare a ubuntu 16.04, or other linux system that there is nano editor no it.

step2: create new tmux session

tmux new -s test

step3: yank nano command in that tmux session

nano

step4: how to exit nano now?

Required information

Please provide the following information:

• tmux version (tmux -V).
  2.1

• Platform (uname -sp).
  Linux x86_64

• $TERM inside and outside of tmux (echo $TERM).
  xterm-256color

The usual solution is to bind the key to send the prefix. For example, this is from my ~/.tmux.conf:

# Use [ctrl-space] rather than [ctrl-A] because the latter conflicts with
# emacs key bindings. And I find [ctrl-space] is easier to type on my various
# keyboards than [ctrl-b].
set-option -g prefix C-Space
unbind C-b
bind C-Space send-prefix

Obviously replace C-Space with C-X. However, you might want to consider using C-Space because it is less likely to ever need to be passed to a program running inside a tmux session.
