docs/data/reusables/copilot/about-code-referencing.md

If you've allowed suggestions that match public code, {% data variables.product.prodname_copilot %} can provide you with details of the code that a suggestion matches. This happens:

• When you accept a code completion suggestion in the editor.
• When a response in {% data variables.product.prodname_copilot_chat_short %} includes matching code.
