<p>This tests modifying a selection created with a double click with shift arrow key.</p>
<p style="color:green">
    This test does not run interactively.
    It uses the event sender to do mouse clicks.
    To run it manually, double click on the blue "g", then press shift-left-arrow twice.
    Then repeat those steps again.
    The selection should include the words "a paragraph" on mac and "paragra" on win/linux..
