I assembled a custom line symbology for my overhead utility lines and used the "Save symbol to style...". I then had a symbology in Favorites. I later had a reason to change the symbology to the layer. How do I remove/delete this saved symbology? Or do I have to live with this now unneeded symbology clogging the favorites category for the life of this project?
You can remove saved styles in Favorites from the Catalog. If you navigate to Styles and then Favorites, you will see a list of your saved symbology. From here you can delete any styles you no longer wish to keep in Favorites.
