Cursor Tab is the editor's signature autocomplete: instead of completing a single token, it predicts multi-line edits and even where you are likely to jump next, which you accept with Tab. It is one of the features that distinguishes Cursor from a plain editor with a chat sidebar.
Like the rest of Cursor, Tab improves over time through frequent releases, so its behavior and quality shift as the team ships updates.
Why it matters
Tab is where a lot of Cursor's day-to-day speed comes from, and the team iterates on it often. Following Cursor's releases tells you when it gets smarter so you can lean on it more.
