Where to Find Syntax Styler (Important!):
Syntax Styler is located in the Right-Hand Side Panel (Companion Bar) on the far right edge of Google Docs™, Google Slides™, and Google Sheets™ (alongside Calendar, Keep, and Tasks) — NOT in the top "Extensions" menu.

Don't see the side panel? If the side panel is collapsed, look at the very bottom-right corner of your document and click the small arrow button `<` ("Show side panel") to expand it and reveal the emerald Syntax Styler icon!

How to Use:
1.  Highlight the code snippet in your document.
2.  Open the Syntax Styler side panel.
3.  Select your language and theme.
4.  Click "Apply Syntax Highlight" and watch the magic happen!

Perfect for:
- Developers: Share snippets in design docs or internal wikis.
- Educators: Create clean, readable coding assignments and tutorials.
- Students: Format your computer science projects and notes.
- Technical Writers: Build professional documentation within Google Workspace.
