With Auto Label, GeoSync generates annotation for all features in a layer. An Annotation Theme must be created and active in order to use the Auto Label tool.
To Use:
Activate Auto Label. A dialog appears.
Check Selected Features Only to label only a selection rather than the entire layer.
Select Auto Label.
Note: Select Undo to remove labels just applied.
