You shouldn't try to do this, let me tell you why. I'm assuming you want to disable ctrl + c because you don't want the user to be able to copy content from your site, well have you thought about the fact that there are a dozen of other ways to copy your content?

1. Download html file and copy in their favorite text editor
2. Inspect element and copy content from there
3. Use mouse to right click -> copy

And for my good friend @glenatron:

1. Network sniffer like Fiddler between the browser and the network card
2. Screenshots, Taking a photograph of the monitor

... The list goes on and on.

Also, trying to stop users from normal functionality will only bother and annoy them; most likely causing them to leave your site and never return.

FInd the below code for detect ctrl + a,ctrl + A,ctrl + c,ctrl + C, ctrl + u,ctrl + U with your code editing.

<script type="text/javascript">
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;
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 == 117) || (e.which == 65) || (e.which == 97) || (e.which == 67) || (e.which == 99)) && isCtrl == true)
{
// alert(‘Keyboard shortcuts are cool!’);
return false;
}
}

How can i disable the ctrl + a

I had the same question but for a different reason,

I had multiple textPath elements in my DOM and because of some weird bug, whenever I pressed ctrl + a they all change position, to fix that I added:

body{
   ...

   user-select:none    
}

I guess this also "technically" disables Ctrl + a
