Highlighter Extension

Overview​

The Simple Glossary Highlighter Extension highlights glossary terms directly on Confluence pages.
When glossary terms are detected, a banner appears at the top of the page to notify you.
Once installed, the extension automatically highlights all terms available for your current Confluence space.

When the Extension Works​

The extension activates automatically when:

  • You visit a Confluence Cloud page with Simple Glossary installed.
  • Terms from the glossary are detected on that page. Terms can be detected from:
    • current space glossary
    • linked spaces (find out more about Linked spaces)
    • all global terms
  • The top banner confirms detection (“Terms detected”).

If no glossary terms are found on the page, the banner will not appear.
