I 'm answering my own question, but when I figured it out, I thought 
others would like to know.
This will disable the control key from being pressed at all. It can be 
modified to disable any key as long as you know they keyCode. (Not sure 
if it works in Netscape.)
<script>
function validateKey (evt) 
	{
		if (evt.keyCode == '17')
		{
			alert("You may not cut and paste text here.")
			return false
		}
		return true
	}
</script>
within the body:
<INPUT TYPE="text" NAME="field" ONKEYDOWN="return validateKey(event)">
So users no more can press ctrl+t to open a new tab or ctrl+w to close
this one, or such. Angry enough yet?
The users still can rightclick and pick "paste". I can disable this by
disabling right mouse button. So they can't execute mouse gestures, they
can't pick "bookmark this page" etc. Should be angry enough by now.
Now all the users have to do is to pick Edit>Paste from the browser
menu. Or go to some less annoying page. You can't block either.
