<h2>&lt;textarea&gt; focus selection</h2>

<p>This test checks whether the selection is restored, cleared, or set
to the full range when using different ways to focus a text
area. These results all match Mozilla. When running manually, please
follow the steps below. In the test harness, the test runs
automatically.</p>

1) Hit tab, only the word "SUCCESS" should be selected:
<textarea id="first">FAILURE or SUCCESS</textarea>
<script>
    var first = document.getElementById("first");
    first.focus();
    first.setSelectionRange(11, 18);
    first.blur();
</script>

<br>

2) Hit Ctrl-Option-J (or Alt-J on Windows), only the word "SUCCESS" should be selected:
<textarea id="second" accesskey="j">FAILURE or SUCCESS</textarea>
<script>
    var second = document.getElementById("second");
    second.focus();
    second.setSelectionRange(11, 18);
    second.blur();
</script>

<br>

3) <input type="button" onclick="document.getElementById('third').focus()" value="Click this button">, only the word "SUCCESS" should be selected:
<textarea id="third">FAILURE or SUCCESS</textarea>
<script>
    var third = document.getElementById("third");
    third.focus();
    third.setSelectionRange(11, 18);
    third.blur();
</script>

<br>

4) Click in the input field, nothing should be selected:
<textarea id="fourth">FAILURE and FAILURE</textarea>
<script>
    var fourth = document.getElementById("fourth");
    fourth.focus();
    fourth.setSelectionRange(11, 18);
    fourth.blur();

<br>

5) <label id="fifthLabel" for="fifth" style="color: blue">Click this label, only the word "SUCCESS" should be selected:</label>
<textarea id="fifth">FAILURE or SUCCESS</textarea>
<script>
    var second = document.getElementById("fifth");
    fifth.focus();
    fifth.setSelectionRange(11, 18);
    fifth.blur();
</script>

<br>

6) <label id="sixthLabel" for="sixth" accesskey="u">Hit Ctrl-Option-U (or Alt-U on Windows), only the word "SUCCESS" should be selected:</label>
