MCU: View options–Record Labels The record labels are simple captions that the program maintains above the two records being displayed. For Self-PLP, these labels are superfluous. For PLP, the label on the left pane is taken from the current Library Load profile, and the label on the right pane will always say 'DB' record1):
The purpose of these labels is simply to provide a visual hint about the actual source of the records being reviewed.
You can change the Font, Color, etc., for this label via the 'Configure|Advanced display options' menu.
