Ready to unlock Cursor's full potential? This comprehensive guide covers advanced techniques, hidden features, and power-user workflows that will transform how you code. Whether you're a seasoned developer or looking to level up your skills, these techniques will supercharge your productivity.
Master the art of placing multiple cursors for maximum efficiency:
// Select all instances of a variable
// Ctrl/Cmd + D - select next occurrence
// Ctrl/Cmd + Shift + L - select all occurrences
const userName = "john";
const userEmail = "john@example.com";
const userProfile = { name: userName, email: userEmail };
// Use Ctrl/Cmd + D to select all "user" prefixes and modify simultaneously
// Alt + Shift + drag for column selection
// Perfect for editing multiple lines with similar structure
const config = {
apiUrl: "https://api.example.com",
apiKey: "your-api-key-here",
apiVersion: "v1",
apiTimeout: 5000
};
// Select the "api" column and change all at once
// Cursor technique for refactoring object structures
const oldStructure = {
user: { name: "John", age: 30 },
product: { name: "Widget", price: 19.99 },
order: { id: 123, status: "pending" }
};
// Use multi-cursor to simultaneously add new properties:
const newStructure = {
user: { name: "John", age: 30, id: 1 },
product: { name: "Widget", price: 19.99, id: 2 },
order: { id: 123, status: "pending", customerId: 1 }
};
// Multi-cursor technique for creating component variations
<Button variant="primary" size="sm" />
<Button variant="secondary" size="md" />
<Button variant="outline" size="lg" />
// Place cursors at each variant/size and modify in bulk
// Technique: Provide rich context for better AI assistance
// Before asking AI for help, structure your code like this:
interface UserPreferences {
theme: 'dark' | 'light';
language: string;
notifications: boolean;
}
class UserService {
// AI Prompt: "Add a method to update user preferences with validation"
// The AI will understand the interface and generate appropriate code
}
// Start with a basic function
function calculateTotal(items) {
// AI Prompt: "Add tax calculation and discount logic"
}
// Let AI build incrementally
function calculateTotal(items, taxRate = 0.08, discountPercent = 0) {
const subtotal = items.reduce((sum, item) => sum + item.price, 0);
const discount = subtotal * (discountPercent / 100);
const discountedTotal = subtotal - discount;
const tax = discountedTotal * taxRate;
return discountedTotal + tax;
}
// Technique: Use AI for complex refactoring tasks
// Original legacy code
function processUser(data) {
if (data && data.user && data.user.profile) {
const name = data.user.profile.firstName + ' ' + data.user.profile.lastName;
const email = data.user.profile.email;
if (email && email.includes('@')) {
return { name, email, valid: true };
}
}
return { valid: false };
}
// AI Prompt: "Refactor this to use modern TypeScript with proper types and error handling"

// Technique: Chain multiple Cursor actions for complex operations
// 1. Search for all function declarations: /^function\s+\w+/
// 2. Multi-cursor on each function name
// 3. Wrap with try-catch using snippet
// 4. Add logging with another snippet
// 5. Format code automatically
// Before:
function calculatePrice(items) {
return items.reduce((sum, item) => sum + item.price, 0);
}
// After (using macro-style workflow):
function calculatePrice(items) {
try {
console.log('calculatePrice called with:', items);
const result = items.reduce((sum, item) => sum + item.price, 0);
console.log('calculatePrice result:', result);
return result;

# Find all React components with props
^(export\s+)?(const|function)\s+[A-Z]\w*.*Props
# Find all async functions
async\s+(function\s+\w+|\w+\s*=|\(\s*\w*\s*\))
# Find TODO comments with priority
TODO:\s*(HIGH|CRITICAL|URGENT)
# Find unused imports (basic pattern)
^import\s+.*from\s+['"][^'"]*['"];?\s*$
// Use Cursor's semantic search for concept-based queries
// Search: "error handling patterns"
// Search: "state management logic"
// Search: "API response processing"
// Search: "component lifecycle methods"
// This helps find code by intent, not just syntax
// Technique: Use Go to Symbol (Ctrl/Cmd + Shift + O) effectively
class UserService {
// Type '@' for methods: @getUserById
private async getUserById(id: string) { }
// Type '#' for properties: #apiClient
private apiClient: HttpClient;
// Type ':' for line numbers: :42
}
// Advanced file switching techniques:
// Ctrl/Cmd + P -> file names
// Ctrl/Cmd + Shift + P -> command palette
// Ctrl/Cmd + T -> workspace symbols
// Alt + Left/Right -> navigate history
// Use breadcrumbs for nested navigation:
// src > components > ui > Button > variants > primary
// Technique: Generate related code patterns
// Base interface
interface User {
id: string;
name: string;
email: string;
createdAt: Date;
}
// AI Prompt: "Generate CRUD operations for User interface"
// Results in complete service class with all operations
class UserService {
async createUser(userData: Omit<User, 'id' | 'createdAt'>): Promise<User> {
const user: User = {
id: generateId(),
...userData,
createdAt: new Date()
};
return await this.save(user);
}
async getUserById(id: string): Promise<User | null> {
return await this.findById(id);
}
async updateUser(id: string, updates: Partial<User>): Promise<User> {
return await this.update(id, updates);
}
async deleteUser(id: string): Promise<boolean> {
return await this.delete(id);
}
}
// Technique: Create reusable patterns for common scenarios
// State machine pattern
type StateTransition<T> = {
from: T;
to: T;
condition?: () => boolean;
action?: () => void;
};
// Form validation pattern
type ValidationRule<T> = {
field: keyof T;
validator: (value: any) => boolean;
message: string;
};
// Repository pattern
interface Repository<T> {
findById(id: string): Promise<T | null>;
findMany(criteria: Partial<T>): Promise<T[]>;
create(entity: Omit<T, 'id'>): Promise<T>;
update(id: string, updates: Partial<T>): Promise<T>;
delete(id: string): Promise<boolean>;
}
// Technique: Structure code to get better AI completions
// Provide clear context
const apiConfig = {
baseUrl: 'https://api.example.com',
timeout: 5000,
retries: 3
};
// AI will suggest appropriate methods based on context
class ApiClient {
// Type: "async fetch" - AI suggests complete fetch implementation
async fetchUser(id: string) {
// AI understands the context and suggests appropriate error handling
}
}
// Techniques for working with large files efficiently
// 1. Use code folding strategically
// 2. Employ breadcrumb navigation
// 3. Use outline view for structure
// 4. Split editor for side-by-side comparison
// 5. Use minimap for quick navigation
// Example: Large configuration file
const massiveConfig = {
// Fold this section when not needed
database: {
// 100+ lines of database config
},
// Keep this section open when working on it
api: {
endpoints: {
users: '/api/users',
// Current work area
}
}
};
// Techniques for managing editor memory with large projects
// 1. Close unused tabs regularly
// 2. Use workspace-specific settings
// 3. Disable extensions for specific languages you don't use
// 4. Use .cursorignore to exclude large directories
// .cursorignore example:
// node_modules/
// dist/
// build/
// *.log
// coverage/
// Technique: Perform bulk operations efficiently
// Instead of individual replacements:
// 1. Use Find & Replace with regex
// 2. Multi-cursor selection
// 3. AI-assisted batch transformations
// Example: Converting all var declarations to const/let
// Regex find: \bvar\s+(\w+)\s*=\s*([^;]+);
// Replace with: const $1 = $2;
// Technique: Strategic breakpoint placement
function complexDataProcessor(data: any[]) {
// Breakpoint 1: Input validation
if (!Array.isArray(data)) return [];
const processed = data
// Breakpoint 2: Filter stage
.filter(item => item.isValid)
// Breakpoint 3: Transform stage
.map(item => transformItem(item))
// Breakpoint 4: Final result
.sort((a, b) => a.priority - b.priority);
return processed;
}
// Technique: Use conditional breakpoints effectively
function processLargeDataset(items: Item[]) {
for (let i = 0; i < items.length; i++) {
const item = items[i];
// Conditional breakpoint: item.id === 'problematic-id'
// Only breaks when specific condition is met
const result = processItem(item);
// Log point: console.log('Processed item:', item.id, result)
// Logs without stopping execution
}
}
// Technique: Use AI to analyze complex errors
try {
await complexAsyncOperation();
} catch (error) {
// AI Prompt: "Analyze this error and suggest solutions"
// Provide the full error context to AI
console.error('Operation failed:', {
error: error.message,
stack: error.stack,
context: {
userId: currentUser.id,
operation: 'complexAsyncOperation',
timestamp: new Date().toISOString()
}
});
}
// Technique: Structure code for better reviews
// Good: Clear, reviewable changes
interface UserConfig {
// Added: New preference for dark mode
theme: 'light' | 'dark';
// Modified: Extended language options
language: 'en' | 'es' | 'fr' | 'de';
// Unchanged: Existing notification setting
notifications: boolean;
}
// Use comments to explain complex logic for reviewers
function calculateComplexMetric(data: MetricData): number {
// Algorithm explanation for reviewers:
// 1. Normalize input data (0-1 scale)
// 2. Apply weighted scoring
// 3. Account for seasonal adjustments
const normalized = normalizeData(data);
const weighted = applyWeights(normalized);
return adjustForSeason(weighted);
