title: HTML5: How to make a form submit, after pressing ENTER at any of the text inputs?
body: <p>The title speaks for itself... I have a couple of forms, one of them is just a single text input form and the other one is composed by two text inputs. I do not want any <em>submit button</em> in any of them, I want each form to submit whenever the user presses the ENTER button at any text input:</p>
  
  <ol>
  <li>The form composed by just one input submits everytime the user presses the ENTER button - <strong>Perfect!</strong></li>
  <li>The second form composed by two text inputs does not behave this way, it does not submit when the user presses the ENTER button at any of both inputs.</li>
  </ol>
  
  <p>Is there a way to make a form <strong>with more than one text input</strong> behave this way and avoid having a <em>submit button</em> in it?</p>
