Cursor AI Tips — Community Guide
Keyboard Shortcuts & Navigation
Essential shortcuts every Cursor user should know:
- Layout switching and multi-pane management
- Navigation between files, symbols, and references

Composer Mode Mastery
Composer is Cursor's multi-file editing feature. Community tips:
- Context management — How to give Composer the right files without overwhelming it
- Agent capabilities — When to use Agent mode vs. standard Composer
- Cost optimization — Budget model selection to reduce API costs
- Multi-file patterns — Effective workflows for large refactors
.cursorrules Configuration
The .cursorrules file is the single most impactful Cursor optimization:
- What to include: preferred patterns, libraries to avoid, naming conventions, error handling style
- Framework examples: React, Next.js, Vue, Python, Go, Rust
.mdcformat: The new Markdown Configuration format (evolution of.cursorrules)- Community impact: developers report going from 30% to 80%+ acceptance rate with a good rules file
Model Selection & Pricing
