title: Google maps V3 API key usage
body: <p>Sounds stupid, but since there is no specific example in documentation, its not clear how to use the api key. <br />
  <strong>This part of code from <a href="https://developers.google.com/maps/documentation/javascript/tutorial?hl=cs" rel="nofollow">documentation</a> is not clear:</strong></p>
  
  <pre><code>&lt;script type="text/javascript"
        src="https://maps.googleapis.com/maps/api/js?key={API_KEY}&sensor=SET_TO_TRUE_OR_FALSE">
      &lt;/script>
  </code></pre>
  
  <p>Well I will find my apikey, let's say that the value of my api key will be for example: 123456ABCDEFG</p>
  
  <p>So how should I used it?</p>
  
  <p>1)<code>src="https://maps.googleapis.com/maps/api/js?key={123456ABCDEFG}&amp;sensor=false"</code><br />
  <strong>or</strong> <br />
  2)<code>src="https://maps.googleapis.com/maps/api/js?key=123456ABCDEFG&amp;sensor=false"</code>
  <br />
  or else?</p>
