Arrow annotations are visual tools that allow users to draw attention to specific elements within a PDF by using arrows as directional indicators. These annotations are especially useful for guiding readers through complex diagrams, workflows, or technical illustrations where clarity is critical. By pointing to key areas, arrows help eliminate confusion, ensure important details aren't overlooked, and streamline communication during document reviews or collaborative discussions. Common use cases include annotating engineering schematics, marking areas for revision in design drafts, and highlighting specific data points in reports.
