Implementing Command Palettes

Overview

Command palettes (Cmd+K / Ctrl+K) need precise keyboard navigation, scroll behavior, and stable references to avoid re-render loops. This skill covers the mechanical patterns that make command palettes feel responsive.

When to Use

• Building a Cmd+K command palette in React
• Implementing arrow key navigation with visual selection
• Keeping selected items visible during keyboard navigation
• Filtering commands by label text AND keyboard shortcuts
• Experiencing infinite re-renders when commands update
