<p>Use your pointing device to <strong>drag the selected text</strong> to the pink box, then release it. While dragging, the drag placeholder should show that only the selected text is being dragged.</p>
<p>(If no text is selected, you will need to use your browser's functionality to select &quot;text dummy&quot; in the orange box.)</p>
