title: Using git with 2 laptops and multiple identities
body: <p>I started a project on my office computer. Now I'm trying to move development to my home laptop. But my home laptop already has keys of own (for several other projects). </p>
  
  <p>This particular project is on bitbucket. Others on this computer are on assembla and several other places.  So I thought about trying to create keys in addition to id_rsa (existing set) for my office key. </p>
  
  <p>I did exactly that, but my keys are called <code>bitbucket</code> instead of <code>id_rsa</code>. So I created <code>config file</code> in <code>~/.ssh</code> and put this code in it with proper indentation. I'm using Tower for GIT and it gives me error: </p>
  
  <pre><code>Warning: Permanently added 'bitbucket.org,' (RSA) to the list of known hosts.
  Permission denied (publickey).
  fatal: The remote end hung up unexpectedly
  </code></pre>
  
  <p>Now I am not sure if this was all I had to do. Did I miss some step? How do I go about it. </p>
