Is there any way to disable the CTRL+C command for certain user roles?
I want to disable it for all user roles except for administrators as administrators need to use it quite often.
This will help somehow reduce the content theft.

is content available to anon users ? if so, then the idea is pointless. beyond that screen captures can be acquired even if CTRL-C is disabled.

Yes, it's a little silly, but if it makes them feel better (and perhaps dissuades a few people from copying content because of the slightly increased difficulty...) why not?

To make an example, let's say you only want to disable CTRL+C for anonymous users. You'll need to add some code to the head of your page template that goes something like:

<?php
global $user;
if($user->uid == 0){
  print "<script style="text/javascript">
  function onKeyDown() {
    var pressedKey = String.fromCharCode(event.keyCode).toLowerCase();
    if (event.ctrlKey && (pressedKey == "c" || 
                          pressedKey == "v")) {
      event.returnValue = false;
    }
  } 
</script>";
}

?>

And, similarly, add an onload attribute to your body tag that calls onKeyDown();
