title: Python mechanize, following link by url and what is the nr parameter?
body: <p>I'm sorry to have to ask something like this but python's mechanize documentation seems to really be lacking and I can't figure this out.. they only give one example that I can find for following a link:</p>
  
  <pre><code>response1 = br.follow_link(text_regex=r"cheese\s*shop", nr=1)
  </code></pre>
  
  <p>But I don't want to use a regex, I just want to follow a link based on its url, how would I do this.. also what is "nr" that is used sometimes for following links?</p>
  
  <p>Thanks for any info</p>
