title: python selenium example doesn't work, says no module named Keys
body: <p>I installed selenium via pip on a windows machine.</p>
  
  <p>Just tryout out the sample on the website:</p>
  
  <pre><code>http://pypi.python.org/pypi/selenium
  
  from selenium import webdriver
  from selenium.common.exceptions import NoSuchElementException
  from selenium.common.keys import Keys
  import time
  
  browser = webdriver.Firefox() # Get local session of firefox
  browser.get("http://www.yahoo.com") # Load page
  assert browser.title == "Yahoo!"
  elem = browser.find_element_by_name("p") # Find the query box
  elem.send_keys("selenium" + Keys.RETURN)
  time.sleep(0.2) # Let the page load, will be added to the API
  try:
      browser.find_element_by_xpath("//a[contains(@href,'http://seleniumhq.org')]")
  except NoSuchElementException:
      assert 0, "can't find seleniumhq"
  browser.close()
  </code></pre>
  
  <p>I changed from time to import time and the error it was giving for that went away, now I am getting:</p>
  
  <pre><code>Traceback (most recent call last):
   File "test.py", line 3, in module
  from selenium.common.keys import Keys
  ImportError: no module named Keys
  </code></pre>
  
  <p>Is the sample out of date?</p>
