title: Tmux does not work in ZSH shell in arch linux
body: <p>Initially, I had tmux working in bash shell.  Then, I installed the zsh shell and changed the default shell to zsh with the following line:</p>
  
  <p><code>#set shell</code><br>
  <code>set-option -g default-shell /usr/bin/zsh</code></p>
  
  <p>Then, I noticed that tmux would not work.  For instance, after getting into tmux, pressing <code>ctrl+b+"</code> displayed a yellow bar at the bottom with "index" on it.</p>
  
  <p>Since then, I have made several modifications to tmux.conf and now I do not know the settings for the default tmux.conf. I tried removing and reinstalling tmux but the tmux.conf file still remains the same.</p>
  
  <p>Any suggestions would be very much appreciated.
  Thanks.</p>
