Next line on enter key but not submit form?

[PGTibs]

I've had a look and the only visible way to stop a form from submitting on the enter key pressed is javascript, however, upon using

 

onkeydown='return event.keyCode != 13 && event.which != 13;'

 

The textarea wont move down another line. Is there a way to make the textarea move down lines, add those extra lines too the sql database AND disable enter key submitting the form?

 

Thanks
