  <title>Live Regions</title>
  <p>
    A live region is a dynamically-updated portion of a web page, such as a
    table of sports statistics, a list of current stock prices, a log from
    a chat, or an alert displayed by the page you are reading. While live
    regions appear quite frequently, fully accessible web pages with live
    regions are encountered less often. This problem is actively being
    addressed by a number of organizations.

    <title>Live Region Politeness Levels</title>
    <p>
      Live regions have an associated "politeness" level which is set by the
      author as a means to convey the importance of the information and to
      suggest when users should be informed by their assistive technology of
      updates made within that region. Live regions can be "off", "polite", or
      "assertive" to the point of being "rude."

    <title><app>Orca</app>'s Support for Live Regions</title>
    <p>
      Because you might not agree with the politeness level specified by the
      author whose page you are viewing, <app>Orca</app> provides a number of
      <link xref="commands_live_regions">live region commands</link> which
      allow you to modify the level of any or all of the regions on a page.
      In addition, you can:
    </p>
    <list>
      <item>
        <p>Turn live region support on or off</p>
      </item>
      <item>
        <p>Jump to the next and previous live region spatially</p>
      </item>
      <item>
        <p>Jump to the last live region which presented information</p>
      </item>
      <item>
        <p>Review the last nine live region messages which were presented</p>
    </item>
