  // A single text field. In IE, when a form has only one non-button input field
  // and the ENTER key is pressed while that field has focus, the form is
  // submitted without any information identifying the button responsible for
  // the submission. In other browsers, the form is submitted as though the
  // first button were clicked.

  // in the argument. For example, if the path is
  // form-test/clicked-button/s/i/rb, then 3 buttons are added: a 'submit', an
  // 'image_button', and a 'button' with #access=FALSE. This enables form.test
  // to test a variety of combinations.
