+## Formatting your messages
+
+The Chat input supports a markdown editor with formatting tools to help you structure longer messages and prompts.
+
+### Slash command menu
+
+Type `/` in the chat input to open a searchable formatting menu. The menu includes 9 options:
+
+- Headings (H1, H2, H3)
+- Bulleted and numbered lists
+- Blockquotes
+- Code blocks
+- Dividers
+- Table of contents
+
+Start typing after `/` to filter the list and quickly find the format you need. Select an option to insert the corresponding block at your cursor position.
+
+### Table of contents block
+
+The table of contents block creates a live, clickable outline of all headings in your message. It updates automatically as you add or change headings, making it useful for long-form content like detailed briefs, structured prompts, or documentation drafts. Insert it via the slash command menu by typing `/` and selecting **Table of contents**.
