title: Created tab always open the url in the same tab
body: <p>I have the following <code>sample.js</code> for Google Chrome extension and I would like to know if there is a way that make it able to open url in the same tab every time:</p>
  
  <pre><code>function getword(info,tab) {    
      chrome.tabs.create({ 
          url: "http://translate.google.com/#en/ar/" + info.selectionText,
      })
  }
  
  chrome.contextMenus.create({
      title: "Translate: %s", 
      contexts:["selection"], 
      onclick: getword,
  
  });
  </code></pre>
  
  <p>The extension send the selected text on the page to be translated on Google translate and I want every time the user uses it to open in the same Window's tab.</p>
