Viewing hidden objects
The filter bar (shown by clicking the “Set up Window Layout” button on the toolbar and activating the Filters option) contains two options related to hidden objects:
If you activate the “Hidden Notes” option, all hidden notes in the score are shown. Deactivating “Hidden Notes” hides the notes again.
If you activate the “Hide” option, all hidden objects (except notes) are indicated by a “Hide” text marker.
