How can I disable Ctrl+A (select all) using jquery in a browser?
<p>I'm trying to prevent information to be copied from a page (for non-technical users of course). I know how to <a href="http://chris-barr.com/entry/disable_text_selection_with_jquery/" rel="nofollow">disable selecting text</a> using the mouse. The following jquery code works:</p>

<pre><code>$(function(){
  $.extend($.fn.disableTextSelect = function() {
    return this.each(function(){
      if($.browser.mozilla){//Firefox
        $(this).css('MozUserSelect','none');
      }else if($.browser.msie){//IE
        $(this).bind('selectstart',function(){return false;});
      }else{//Opera, etc.
        $(this).mousedown(function(){return false;});
      });
    });
    $('.noSelect').disableTextSelect();
});
</code></pre>

<p>But users can still use Ctrl+A to select the entire page. Any workarounds for this?</p>
