In the dialog, select Names from the drop-down box as the Label Field and click the Use Theme's Text Label Placement Property radio button. Check the Scale Labels box. Click on OK and watch your labels appear. Zoom and then out. Observe how the font expands and contracts as the scale changes.
Many labels overlap when using the scale and font parameters suggested above.
Remove all labels by selecting Theme, then Remove Labels from the menu. Again, select Theme, then Auto-label from the menu. After specifying Name as the label field, select Find Best Label Placement and Allow Overlapping Labels. This time most labels are centered above the GNIS point, and overlapping labels are green. Turning the GNIS Points theme off removes these symbols and graphics from the view.
