Ten workflows that will transform how you code with Copilot:

1. Write a comment describing a function → Tab to accept the whole implementation
2. Paste an error message into chat → /fix
3. Select a function → /tests for instant test coverage
4. Select code → /explain when confused
5. Type @workspace + question to navigate unfamiliar codebases
6. Select code → /doc for instant documentation
7. Ask Copilot to write the boilerplate, then customize
8. Use inline chat (Ctrl+I) to refactor a selection
9. Ask "what are the edge cases for this function?"
10. Use Copilot CLI for shell commands you can never remember
