# Cursor Tab Completion Master Cursor's AI-powered Tab completion system. Tab uses a specialized Cursor model trained for inline code prediction -- it learns from your accept/reject behavior to improve over time. ## How Tab Works 1. You type code in the editor 2. Cursor's model predicts what comes next based on: current file, open tabs, recent edits, project rules 3. Ghost text (gray text) appears inline 4. You decide: **Tab** to accept, **Esc** to dismiss ``` // You type: function validateEmail(email: string) // Ghost text appears: function validateEmail(email: string): boolean { const emailRegex = /^[^\s@]+@[^\s@]+\.[^\s@]+$/; ← gray ghost text return emailRegex.test(email); } ``` ## Key Bindings | Action | macOS | Windows/Linux | |--------|-------|---------------| | Accept full suggestion | `Tab` | `Tab` | | Accept word-by-word | `Cmd+→` | `Ctrl+→` | | Dismiss suggestion | `Esc` | `Esc` | | Force trigger | `Ctrl+Space` | `Ctrl+Space` | **Word-by-word acceptance** (`Cmd+→`) is powerful for partial suggestions. If the AI suggests a complete function but you only want the signature, accept word-by-word until you have what you need, then type your own body. ## Tab Completion Settings Access via `Cursor Settings` > `Tab`: | Setting | Purpose | Recommendation | |---------|---------|----------------| | Tab Completion | Master on/off toggle | Keep enabled | | Trigger in comments | Generate comment text | Disable for less noise | | Accept suggestion keybinding | R...
