Tab Completion

Inline AI suggestions that predict what you\u2019ll type next \u2014 from single tokens to entire functions.

What's possible

  • Complete function bodies from a signature or comment
  • Finish repetitive patterns (imports, switch cases, test assertions)
  • Predict the next line based on surrounding code context
  • Accept partial suggestions word-by-word
  • Multi-line block completions for loops, conditionals, and handlers

Getting started

  1. 1

    Start typing code

    As you type, Cursor predicts what comes next and shows ghost text inline. Suggestions appear automatically — no shortcut needed.

  2. 2

    Accept with Tab

    Press Tab to accept the full suggestion. Press Ctrl+Right Arrow to accept word-by-word for partial acceptance.

  3. 3

    Reject with Escape

    Press Escape or keep typing to dismiss the suggestion. Cursor will generate a new one based on your updated context.

  4. 4

    Multi-line completions

    Tab can suggest entire blocks — function bodies, conditionals, loops. Accept the first line and Tab again to continue.

Example scenarios

From a function signature

“function calculateTax(income: number, rate: number): number {”

From a comment

“// Sort users by last name, then first name”

Completing a pattern

“const [loading, setLoading] = useState(false);”

Tips

  • Write descriptive function names and comments \u2014 Tab uses them as context for better predictions.
  • Tab learns from your current file and open tabs. Keep related files open for better suggestions.
  • If suggestions are too aggressive, adjust the Tab completion settings in Cursor Settings.
  • Tab works best for boilerplate and patterns. For complex logic, use Chat or Composer instead.
