Frequently Asked Questions

Can I start numbering from something other than 1?

Yes. Set any starting number, which is useful when continuing from a previous block or matching line numbers from a specific file offset.

What is zero padding for?

Alignment. With 120 lines, padding to three digits makes 001 through 120 line up in a monospaced font, so the text does not stagger.

How do I remove existing line numbers?

Switch to remove mode. It strips a leading number and its separator from each line, which is how you clean up code pasted from a viewer that included them.

Should blank lines be numbered?

For code review, yes — the numbers must match the file. For lists, usually not. Both behaviours are available.
