    <p>This is a manual test, since there's no way to synthesize keyboard or
    mouse input.  Click after the letter "c" in the following paragraph and
    drag backwards so that both the "b" and the "c" are highlighted, then click
    the "Test" button:

    <p>abcd <button onclick=testDirection()>Test</button>
