title: How and where to insert Google Translate API key in OmegaT 3.1.3 (Mac OSX 10.9)?
body: <p>I use OmegaT 3.1.3, on Mac OSX 10.9
  I activated my billing info, Google Translate service, and created a new key.
  I inserted my API Key in the file Info.plist, file located under Applications/OmegaT.app right click Show package contents  /Contents/
  I added before  the followings lines:</p>
  
  <pre><code>&lt;key&gt;apple.awt.graphics.UseQuartz&lt;/key&gt;
  &lt;string&gt;true&lt;/string&gt;
  &lt;key&gt;google.api.key&lt;/key&gt;
  &lt;string&gt;**my api key**&lt;/string&gt;
  </code></pre>
  
  <p>I reloaded OmegaT but it keeps showing this message:</p>
  
  <pre><code>Google Api key not available. See OmegaT manual for instructions. 
  &lt;Google Translate v2&gt;
  </code></pre>
