title: Clean way to prevent enter button submitting a form
body: <p>I've seen a lot of Javascript solutions to do this, but I'm sure there must be an easier way.</p>
  
  <p>I have a really simple form - one multiline textbox and a submit button. I want the user to be able to submit "formatted" text (i.e. like an email, with paragraphs, new lines etc)</p>
  
  <p>However, when the user hits Enter to put in a carriage return it submits the form.</p>
  
  <p>I'm there there must be a property or something that controls this, as this must be a common issue. Javascript as a solution seems a bit too complex.</p>
