title: Webaccessibility - Suggestions needed
body: <p>Visiting the following site in IE:</p>
  
  <p><a href="http://www.oebb.at" rel="nofollow">http://www.oebb.at</a></p>
  
  <p>In the header section one can see the plus(+) symbol. By clicking on it the the font size and the images will be enlarged. And similarly clicking on (-) symbol the sizes will be reduced.</p>
  
  <p>I would like to know what will be the best way to implement it in my website.</p>
  
  <p>Similarly, pressing Alt + 0 one sees an options list to directly access different areas of the website.
  For example by pressing Alt+2 the search field will be focused. And by pressing Alt+1 the main menu will be focused.</p>
  
  <p>What is the best possible way to implement this?</p>
