title: How do I scroll in tmux using the mouse?
body: <p>I'm using tmux 1.8 on Mac OS X 1.9.3 in the Terminal.app with an Apple magic mouse. I'm also using oh-my-zsh.</p>
  
  <p>I can't scroll at all with the mouse when tmux is running. It just scrolls the whole terminal window up which goes beyond the output of tmux.</p>
  
  <p>I've tried these settings in the tmux.conf file but nothing works:</p>
  
  <pre><code>set -g mode-mouse on
  setw -g mode-mouse on
  set -g terminal-overrides 'xterm*:smcup@:rmcup@' 
  </code></pre>
  
  <p>I made sure to reload the tmux.conf and also killed a sessions and created new ones just to make sure. And it still doesn't work.</p>
  
  <p>Please help. Here is my entire tmux.conf</p>
