Add Line Numbers FAQ
Why start at something other than 1?
Excerpts: quoting lines 340–360 of a transcript numbered from 340 keeps every reference true to the source — the professional habit this option exists for.
Tab separator — why offered?
Tabs paste into spreadsheets as their own column, so numbered text becomes two clean columns in one paste. Small trick, disproportionate joy.
