Disabling editor on key-press

Hi guys!

I'm working on functionality to edit documents in discrete chunks. To conclude one section and start another a double-tap of the key would be needed. For this, one instance of the editor should be closed and another instance should open.

Now I've got the instance to destroy itself when the second enter is input- however I would really love to remove or disable the placement of te next new line. I've tried canceling the event but it still places a new line anyway.

Here is the code I have so far:

<script>
	var enterkey = false;
	var currentPara;
		
		// Turn off automatic editor creation first
		CKEDITOR.disableAutoInline = true;
		
		CKEDITOR.on('instanceCreated', function(e) {
	        e.editor.on('key', function(evt) {
	                
	                if(evt.data.keyCode == 13)
	                {
	                	if (enterkey) 
	                	{
	                		enterkey = false;
					// [[Save editor contents and create new editor instance]]
					
					// Attempts to prevent a return showing up
	                		CKEDITOR.keystrokeHandler.blockedKeystrokes = [13];
	                		evt.preventDefault();
	                		evt.cancel();

					// Destroy current editor
	                		evt.editor.destroy();
					currentPara.setAttribute("contenteditable", "false");
	                		return false;
	                	}
	                	else
	                		enterkey = true;
	                }
	                else
	                	enterkey = false;
	        });
	    });
</script>
