Why are Zotero citations or bibliographies always highlighted in gray or another color?
Word and LibreOffice will highlight Fields/Reference Marks on your screen to indicate that the text is automatically generated. This can help you avoid accidentally manually typing in the fields (to edit the text shown in a Zotero citation, see Customizing Cites). These highlights are only shown on screen and won't appear if you print or save the document as a PDF.
You can change the settings for highlighting Fields/Reference Marks in your word processor:
- Word for Windows: In Word Options, open “Advanced”, then set “Field shading” to “Never”, “Always”, or “When selected”.
- Word for Mac: Open Word → Preferences → View and set “Field shading” to “Never”, “Always”, or “When selected”.
- LibreOffice: Open Tools → Options → LibreOffice → Application Colors and check/uncheck the “Field shadings” box. You can also control the color used for field shadings.
