Frequently asked questions

Can I change the start number?

Yes: start (e.g. 0 or 1), step (increment between numbers) and separator (dot, paren, colon or tab) are all adjustable.

What is zero-padding for?

It pads numbers with zeros (01, 02, …, 10) so they all share the same width — handy for clean alignment.

Are empty lines numbered?

By default yes. Enable “Skip empty lines” to number only lines that contain text.
