| This test checks that using the keyboard in a way that does not move focus still causes <code>:focus-visible</code> matching to trigger. |
| <ol id="instructions"> |
| <li>If the user-agent does not claim to support the <code>:focus-visible</code> pseudo-class then SKIP this test.</li> |
| <li>Use the mouse to focus the element below that says "Click me."</li> |
| <li>If the element has a red outline, then the test result is FAILURE.</li> |
| <li>Press the ENTER key.</li> |
| <li>If the element now has a green outline and not red background, then the test result is SUCCESS.</li> |
| </ol> |
