Tab autocomplete is Cursor's most powerful feature for speed. As you type, it predicts what comes next—often multiple lines at a time. The AI learns from your code and patterns.
How Tab Autocomplete Works
Start typing code. After a few characters, a suggestion appears grayed out. This is Cursor's AI predicting your next line(s). Press Tab to accept it.
Accepting and Rejecting Suggestions
- Tab: Accept the entire suggestion
- Escape: Reject and dismiss the suggestion
- Ctrl+→ (or Cmd+→): Accept just the next word
- Delete: Clear the suggestion and keep typing your own code
Pro Tips for Better Suggestions
The better context Cursor has, the better its suggestions:
- Write clear comments: If you write "// Create a button with onClick handler", Cursor will suggest the code to match
- Follow naming patterns: Consistent names help Cursor predict what you're building
- Keep related code nearby: Don't spread imports and usage far apart
- Write function signatures first: Define the function name and parameters, Cursor suggests the body
Example: React Component
Type this and watch Cursor autocomplete the component:
function Button({ label, onClick }) {Cursor will suggest the rest: return statement, Tailwind classes, etc.
Free vs Pro: Autocomplete Limits
On the free Hobby plan, Tab is included with limited usage. Paid plans from Pro ($20/month) include unlimited Tab completions.
Tab autocomplete works best on straightforward, predictable code (components, loops, API calls). For bigger changes, ask the agent instead (lesson 5).
