The ⇅ symbol features two vertical arrows side-by-side, with the left arrow pointing up and the right arrow pointing down. In typography and user interface design, it frequently indicates sorting features, vertical swapping, or a two-way exchange of data. While similar to the standard up-down arrow (↕), this paired version visually emphasizes two distinct, simultaneous processes moving in opposite directions.
