Summary

In a feature-linked annotation, the annotation display on the map is updated by re-writing the existing expression or adding a new expression. Depending on the types of changes made, this may cause the annotation to shift.

Instructions provided describe how to annotate multiple fields, change spacing, or add additional text. Instructions do not describe how to update text size, color or font.
