title: zsh shortcut 'ctrl + A' not working
body: <p>I recently switch from bash to zsh shell. To be more precise, the <a href="https://github.com/robbyrussell/oh-my-zsh">oh-my-zsh</a>
  Very nice, but the shortcut I most often use; jumping to the beginning/end of the line doesn't work anymore. From the <a href="http://www.geekmind.net/2011/01/shortcuts-to-improve-your-bash-zsh.html">docs</a> it should be</p>
  
  <pre><code>ctrl + A --&gt; beginning
  ctrl + E --&gt; end
  </code></pre>
  
  <p>However, when I do that I get the following</p>
  
  <pre><code>$~&gt; my-command
  $~&gt; my-command^A   # did a ctrl + A here
  </code></pre>
  
  <p>Although I see this working by everybody else, on my system something seems to be different. Any suggestions what that might be ?</p>
