A developer is using Copilot Chat in VS Code to understand a legacy codebase. They select a complex function and ask 'Explain what this function does.' The response is too high-level. What should they do to get a more detailed, line-by-line explanation?

Open a new chat session and paste the function with the prompt 'Explain this.'

Switch to Copilot agent mode and ask it to refactor the function.

Use the '/explain' slash command with the function selected.

Ask a follow-up question: 'Can you break this down line by line and explain each part?'

What action cycles through alternative inline suggestions from Copilot?

Press Alt+] (or Option+] on macOS).

What is the purpose of configuring content exclusions for GitHub Copilot?

To enable Copilot in more IDEs.

To prevent Copilot from using or suggesting code from specific files or repositories.

To improve Copilot's performance by caching more data.

A developer is using Copilot agent mode to refactor a large function across multiple files. The agent starts making changes, but the developer notices it is also modifying a file that should not be touched. What is the best way to regain control and limit the agent's scope?

Let the agent finish and then revert the unwanted changes with git.

Interrupt the agent and use a more specific prompt that names the files to modify.

Switch to Copilot Chat and ask it to refactor the function without mentioning the file issue.

Disable Copilot entirely and make the changes manually.

A developer wants Copilot to automatically create a new test file, write test cases for a module, and run the tests to verify they pass. Which Copilot feature is best suited for this multi-step task?

Inline suggestions in the test file.

Copilot in the CLI with 'gh copilot suggest'.

Copilot Chat with a prompt to 'write tests'.

Copilot agent mode with a prompt to 'create a test file and run it'.
