// 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.
