title: send_keys(Keys.CONTROL + Keys.TAB) doesn't work in Selenium Python
body: <p>I have been trying to switch tabs on chrome by using the following code. </p>
  
  <pre><code>driverlist = driver.window_handles
  driver.switch_to_window(driverlist[1])
  </code></pre>
  
  <p>which works perfectly fine. But I want write a function when called switches to the next immediate tab, which is I'm trying to use send_keys functions like</p>
  
  <pre><code> from selenium.webdriver.common.keys import Keys
  driver.find_element_by_tag_name('body').send_keys(Keys.CONTROL + Keys.TAB) 
  </code></pre>
  
  <p>I'm expecting send_keys() to switch the tab focus to the next tab but when i print current_url, the focus stays on the previous tab.</p>
