The Add Selection icon shows a dotted rectangular selection frame with a plus sign overlapping its lower-right edge. Drawn in the line style on a 24px grid, its sharp geometry keeps the symbol clear in compact UI controls. Use it for adding selected items, multi-select actions, crop or marquee tools, and selection management. It belongs to Sharp Line - Streamline Material set in the Streamline Material family.
