Auto-balance parentheses

TabNine can automatically balance parentheses, by removing and adding closing parentheses after the cursor. See the examples here.

Default key bindings

M-]	tabnine-next-completion

Known Issues

• TabNine's local deep learning completion might be enabled by default. It is very CPU-intensive if your device can't handle it. You can check by typing "TabNine::config" in any buffer (your browser should then automatically open to TabNine's config page) and disable Deep TabNine Local (you will lose local deep learning completion).
