      <div class="title_division"> Eligibility for Selection</div>
      <p class="para_division"> In this option, every point inside the rectangle you define is eligible for selection unless it is blanked, is on a layer that is invisible or  <em>non-selectable</em>, or is  <em>invisible</em> as a result of being outside the view boundaries. The points must also be selectable in the view of the cursor (e.g., the view in which the start and end points are selected).
      </p>
      <div class="title_division"> Defining the Rectangle</div>
      <p class="para_division"> When you select Chain Within Rectangle, you first define the rectangle by indicating two diagonal corners using the screen cursor.</p>
      <p class="para_division"> Next, the system prompts you to select a start and an end point from among the points within the rectangle. Finally, the system selects and highlights all the points in between.</p>
