title: In Terminal.app, option+arrow keys no longer move by word
body: <p>Having done a little research on this, I know that option+left arrow and option+right arrow <em>do not</em> by default move by word in the OS X Terminal application. But mine did, until about a week ago. </p>
  
  <p>The only thing that's changed is oh-my-zsh updated. I see that it has  </p>
  
  <pre><code>bindkey "^[[1;5C" forward-word  
  bindkey "^[[1;5D" backward-word
  </code></pre>
  
  <p>defined but I don't know what those keys are. GitHub's last recorded change to the file was 24 days go and not related to those keys, so this must predate the latest update.</p>
  
  <p>I have also tried the "Use option as meta key" option under Preferences > Settings > Keyboard. That only results in printing <code>[D</code> and <code>[C</code> when I hit option+left arrow and option+right arrow.</p>
