  <p>The <code>accessKey</code> attribute is available for many components like buttons, checkboxes or links.
    A component with this attribute is accessible by the given character. The character is not case sensitive.</p>
  <p>Logging the accessKey can be configured by setting the category
    <code>org.apache.myfaces.tobago.internal.util.AccessKeyLogger</code> to log level "debug".</p>

  <p>The usage of accesskeys is different for every OS and browser.<br/>
    For example, in the Windows-Firefox, you have to press 'Alt + Shift + key'.
    In Chrome for Mac OS X it's only 'Control + Alt + key'.

    <p>The accesskey is set to 'a'. Notice, that the 'A' in the label of the button has an underscore.</p>

    <p>The accesskey is '3'. Nothing is underlinded, because the value of the label doesn't contain a '3'.</p>
