blackline
Original technical document
Blackline refers to a document comparison showing changes between versions, with deletions and additions marked—typically deletions struck through and additions underlined.
The term comes from legal and business contexts where tracking revisions matters: Send me a blackline against the last draft.
As a verb, to blackline is to produce such a comparison: Can you blackline these two contracts?
