AI Shortcuts in Cursor

AI Chat

Open AI chat panel on the right

Inline Edit

Edit code directly at cursor position

Composer (Agent Mode)

Edit multiple files simultaneously with an AI agent

Tab Autocomplete

Accept AI code suggestions

* On macOS, replace Ctrl with Cmd.

.cursorrules File

Create a .cursorrules file in the project root to provide context and rules for the AI:

# .cursorrules - Ví dụ cho dự án React + TypeScript
## Tech Stack
- React 18 + TypeScript
- Ant Design components
- Tailwind CSS for styling
- React Router v7
## Coding Conventions
- Use functional components with hooks
- Prefer named exports
- Use TypeScript interfaces (not types) for props
- Follow existing patterns in the codebase
## File Structure
- Components in src/components/{Domain}/
- Pages in src/pages/
- API services in src/services/
- Utilities in src/utils/
## Important Notes
- Always use the existing design tokens (space-text, space-primary, etc.)
- Mobile responsive is required (use useMediaQuery hook)
- Vietnamese language for UI text

Troubleshooting

Model not showing in the list

- Check you clicked Save after adding the model
- Restart Cursor IDE
- Check the model name was entered correctly (case-sensitive)

"Request failed" error when chatting

- Check the API Key is entered correctly in Settings → OpenAI
- Check the Base URL ends with /v1
- Ensure you have subscribed to the model on ARZASTORE AI Marketplace
- Check account balance

Slow response or timeout

- Try a lighter model (gpt-4o-mini instead of gpt-4o)
- Check the provider is online on the Marketplace
- Use fallback strategy to automatically switch providers on failure
- Subscribe to another provider for the same model

Tips for Effective Cursor Use

-Use Ctrl+L to chat, then use @file to reference specific files
-Use Ctrl+I (Composer) for multi-file editing tasks — AI will create a diff for each file
-Select code then press Ctrl+K for inline editing of the selected code
-Choose a fast model (gpt-4o-mini) for tab autocomplete and a powerful model (claude-sonnet) for Composer
-Write detailed .cursorrules to help the AI better understand your codebase
