• Labels can be attached to elements, such that, when parameters of the element are changed,
  the text shown in the label will change.
• Procedure:
• Select the element you want to attach the label to (click it either once or twice?)
  click label icon (paper-tag-shaped with dropped ball)
  click in drawing where you want the arrowhead to be
  click where you want end of first line segment to be
  click where text will start
• in View tab, click in Arrow Type field (default will be Dot)
  click drop-down arrow, and select desired shape
• click in Arrow Size field, and scroll to desired size
  click in Text Size field, and scroll to desired size
• in Data tab,
  click in Label Type field, and select "Label"
  click title of field, ie "Label Type" and the change (from default "Label" to whatever is the actual title of the element) should happen
• However:
• If you rename the element, the label does not update automatically
• Here's the convolution I found that works:
  after you've renamed the element, select the label leader
  in Data tab, click in Label Type field, and select a different type, eg. Length
  click the "Label Type" fieldname (ie. 'title of field') and the label in your drawing should change
  repeat the process to return to your desired type, eg. "Label"
