title: Using 'Tab' Key to move down one row
body: <p>I have set-up multiple text fields with javascript</p>
  
  <pre><code>&lt;input type=text name="&lt;%=ID%&gt;" value="&lt;%=valueID%&gt; &gt; 
  
  TextF11    TextF12   TextF13   TextF14
  TextF21    TextF22   TextF23   TextF24 
  TextF31    TextF32   TextF33   TextF34
  </code></pre>
  
  <p>When I fill-out TextF11 and press 'Tab' or 'Down arrow', I want system to focus TextF21.
  Then TextF31.</p>
  
  <p>Is there a way? </p>
