the.com/snapline

The invisible leash that makes your drag actually land where you meant.

means A guide line (or snap-to-grid behavior) that pulls your cursor or object into precise alignment with other elements as you drag.

from A compound built from 'snap' (the sudden, decisive click of parts locking into place, echoing its use since the 1500s for a sharp bite or crack) and 'line' (a marked path or guide, from Latin 'linea'). The term rose with computer-aided design and vector software, where designers needed a word for those temporary alignment guides that lock a dragged object into place the instant it nears a matching edge — a digital echo of carpenters' chalk lines snapped taut against wood to mark a straight cut.
