title: How to fix/restore mouse controls in tmux on iTerm2?
body: <p>I've been playing around with my iTerm2 shell setup. Previously I'd been able to use mouse controls to resize panes, etc. in tmux by simply adding <code>set -g mouse on</code> to <code>.tmux.conf</code>.</p>
  <p>Now, however, it's just not working in iTerm2 (but it is working in the built-in Terminal app). I'm not sure what I did to mess things up. My best guess is that this line that I had used in <code>.tmux.conf</code> was the culprit.</p>
  <pre><code>set -g terminal-overrides 'xterm*:smcup@:rmcup@'
  </code></pre>
  <p>No idea what that syntax means (I copied/pasted from a SO answer). Even when I remove that line from <code>.tmux.conf</code>, the mouse mode still doesn't work. Any ideas how to fix/restore standard tmux-mouse-mode behavior in iTerm2?</p>
