Answer 1

var isCtrl = false;
document.onkeyup=function(e)
{
    if(e.which == 17)
    isCtrl=false;
}
document.onkeydown=function(e)
{
    if(e.which == 17)
    isCtrl=true;
    if((e.which == 85) || (e.which == 67) && (isCtrl == true))
    {
        return false;
    }
}
var isNS = (navigator.appName == "Netscape") ? 1 : 0;
if(navigator.appName == "Netscape") document.captureEvents(Event.MOUSEDOWN||Event.MOUSEUP);
function mischandler(){
    return false;
}
function mousehandler(e){
    var myevent = (isNS) ? e : event;
    var eventbutton = (isNS) ? myevent.which : myevent.button;
    if((eventbutton==2)||(eventbutton==3)) return false;
}
document.oncontextmenu = mischandler;
document.onmousedown = mousehandler;
document.onmouseup = mousehandler;
  

Answer 2

That page uses the following code:

 document.oncontextmenu = function(e) {
   var t = e || window.event;
   var n = t.target || t.srcElement;
   if (n.nodeName != "A") return false
 };
 document.ondragstart = function() {
   return false
 };


 function disableSelection(e) {
   if (typeof e.onselectstart != "undefined") e.onselectstart = function() {
     return false
   };
   else if (typeof e.style.MozUserSelect != "undefined") e.style.MozUserSelect = "none";
   else e.onmousedown = function() {
     return false
   };
   e.style.cursor = "default"
 }
 window.onload = function() {
   disableSelection(document.body)
 }

<div style="height: 150; width: 150">
  <a href="link1.html">link 1</a>
</div>

By the way, you cannot protect Javascript source code from being stolen or viewed, as the person visiting the page must be able to view the script in order to run it.
