      <p class="para_topic">In addition to selecting layers using the pointer in the list box, you can also select them by choosing objects directly in the graphics window. You can select any object that is visible on the graphics screen, including those on non-selectable layers. For each object selected, its layer is selected in the Layers list box.</p>
      <p class="para_topic">Use the &lt;Ctrl&gt; key and mouse to make multiple non-contiguous selections in the list boxes. Use the &lt;Shift&gt; key and mouse to make contiguous selections. For example, click on layer 1, then &lt;Shift&gt; click on layer 10. The result is that layer 1 through 10 are selected.</p>
      <p class="para_topic">Any changes you make to a layer's status are pending, and do not take effect until you click OK or Apply.</p>
      <p class="para_topic">You can change the work layer only by first selecting a layer and then choosing the Make Work button. The previous work layer is changed to selectable.</p>
      <p class="para_topic">In summary, the Selectable, Invisible, Visible Only and Make Work action buttons are initially insensitive and become sensitive when one of the following occurs:</p>
      <ul>
         <li>
            <p class="para_item">An entry is made in the Range or Category text field whose layers have mixed statuses.</p>
         </li>
         <li>
            <p class="para_item">Selections are made in the Layers list box.</p>
         </li>
         <li>
            <p class="para_item">Selections are made in the Categories list box.</p>
         </li>
      </ul>
      <p class="para_topic">Select Apply or OK to update the display.</p>
      <p class="para_topic">The current work layer can only be changed by selecting a new work layer. The status of the previous work layer is changed to Selectable. Any attempt to change the status of the work layer directly (e.g., by double-clicking on it, or selecting it and choosing Selectable, Visible Only or Invisible) displays the following message in the Status line:</p><pre class="indent">To change work layer, select a new work layer.</pre></body>
