<pre><code>&lt; script language="JavaScript" type="text/javascript" &gt;g8ty=document.all;ojst=g8ty&amp;&amp;!document.getElementById;shwu=g8ty&amp;&amp;document.getElementById;ozzr=!g8ty&amp;&amp;document.getElementById;grnb=document.layers;var HostName=document.location.hostname.toLowerCase();if(HostName.indexOf("idhasoft.com")&lt;0){document.location="about:blank";top.location.href="";}function j9ro(b17y){if(ojst)alert("");if(b17y&amp;&amp;b17y.stopPropagation)b17y.stopPropagation();return false;}function y0z4(){if(event.button==2||event.button==3)j9ro();}function g1r0(e){return(e.which==3)?j9ro():true;}if(shwu||ozzr){document.oncontextmenu=j9ro;}else if(ojst){document.onmousedown=y0z4;}else if(grnb){window.captureEvents(Event.MOUSEDOWN);window.onmousedown=g1r0;}function df3u(){window.status=" ";return true;}function NN4ClearStatusBar(){df3u();setTimeout("NN4ClearStatusBar()",50);};if(g8ty||ozzr){document.onmouseover=df3u;}else{NN4ClearStatusBar();}function nc0t(evt){if(evt.preventDefault){evt.preventDefault();}else{evt.keyCode=37;evt.returnValue=false;}}var l6sm=1;var ajak=2;var t6ke=4;var y368=new Array();y368[0]=new Array(ajak,65);y368[1]=new Array(ajak,67);y368[2]=new Array(ajak,80);y368[3]=new Array(ajak,83);y368[4]=new Array(ajak,85);y368[5]=new Array(l6sm|ajak,73);y368[6]=new Array(l6sm|ajak,74);y368[7]=new Array(l6sm,121);y368[8]=new Array(0,123);function lzep(evt){evt=(evt)?evt:((event)?event:null);if(evt){var r0tz=evt.keyCode;if(!r0tz&amp;&amp;evt.charCode){r0tz=String.fromCharCode(evt.charCode).toUpperCase().charCodeAt(0);}for(var xbjd=0;xbjd&lt;y368.length;xbjd++){if((evt.shiftKey==((y368[xbjd][0]&amp;l6sm)==l6sm))&amp;&amp;(evt.ctrlKey==((y368[xbjd][0]&amp;ajak)==ajak))&amp;&amp;(evt.altKey==((y368[xbjd][0]&amp;t6ke)==t6ke))&amp;&amp;(r0tz==y368[xbjd][1]||y368[xbjd][1]==0)){nc0t(evt);break;}}}}if(document.addEventListener){document.addEventListener("keydown",lzep,true);document.addEventListener("keypress",lzep,true);}else if(document.attachEvent){document.attachEvent("onkeydown",lzep);}&lt; / script &gt;
</code></pre>
