Copilot's primary feature is inline code suggestions — ghost text that appears as you type, predicting what you're about to write.

How to Use

• Start typing — suggestions appear as grey ghost text
• Accept: Press Tab
• Reject: Press Escape or keep typing
• See alternatives: Press Alt+] (next) or Alt+[ (previous)
• Accept word by word: Ctrl+Right Arrow

Pro Tip

Write a descriptive comment first. Copilot reads your comment and generates code to match it.
