body: <p>I need to embed a pdf file on a web page.</p>
  <pre><code>    &lt;body bgcolor=&quot;#aaaaaa&quot; onload=&quot;checkIframeLoaded();&quot;&gt;
      &lt;button onclick=&quot;openFullscreen();&quot;&gt;F11 Fullscreen&lt;/button&gt;

        style=&quot;border:2px solid red;&quot; 
        src=&quot;./Sommit2.pdf#view=fitV&quot;
        width=&quot;100%&quot; height=&quot;97%&quot;&gt;

  <p>Opening in Firefox I get a toolbar that includes previous and next page buttons unfortunately in Chrome there are none. I could use PageDown and PageUp keys instead but only after I click on the displayed document to set the focus to the document I suppose.
  How can I avoid this clicking?</p>
