Frequently Asked Questions
Can I start numbering from a number other than 1?
+Yes. Set any start number in the Start Number field. This is useful when continuing a numbered list that starts partway through a document, or when matching line numbers from an existing file.
What does zero padding do?
+Zero padding adds leading zeros to numbers so they all have the same width. For example, line 1 becomes "01" and line 10 stays "10". This keeps columns aligned when viewing in a monospace font.
