🔑 Feature Breakdown
| Feature | Shortcut | Best For |
|---|---|---|
| Tab Autocomplete | Tab | Real-time code completion, multi-line predictions |
| Inline Edit | Cmd+K | Rewrite selected code, fix bugs, add features |
| AI Chat | Cmd+L | Ask questions about selected code or entire project |
| Agent Mode | Cmd+Shift+L | Autonomous task execution, multi-file changes |
| Composer | Cmd+I | Build entire features from natural language |
🚀 5 Productivity Hacks
- 1. Use Agent for refactoring — "refactor this component into smaller pieces with proper TypeScript types" — Agent handles all files
- 2. Cmd+K for unit tests — Select a function, hit Cmd+K, type "write comprehensive unit tests"
- 3. Project-wide search → AI context — Use Ctrl+Shift+F to find relevant code, then @-mention files in Chat
- 4. .cursorrules for consistency — Define project conventions (folder structure, naming, testing framework) once
- 5. Composer for boilerplate — "Create a complete CRUD API with Express + Prisma + TypeScript" — Composer generates all files
