title: Send keys not working in selenium with python
body: <p>send keys are not working in selenium with python.
  This was working earlier but it fails now.
  I don't know what may be the issue . It gives following error :</p>
  
  <pre><code>u"Element is disabled and so may not be used
  for actions\nCommand duration or timeout: 11             
  milliseconds\nBuild info: version: '2.15.0', revision: '15105', time:
  '2011-12-08   09:56:25'\nSystem info: os.name: 'Windows 7', os.arch:
  'amd64', os.version: '6.1',    java.version: '1.6.0_22'
  </code></pre>
  
  <p>I have used below along with <code>time.sleep(3)</code> before passing keys   </p>
  
  <pre><code>elem.send_keys('selenium')   
  elem.send_keys(Keys.RETURN)    
  </code></pre>
  
  <p>Also   </p>
  
  <pre><code>elem.send_keys("Sale" + Keys.RETURN)   
  </code></pre>
  
  <p>But nothing works</p>
