Up Down Arrow With Base Symbol Meaning
↨ (UP DOWN ARROW WITH BASE, U+21A8) is a bidirectional arrow showing movement or linkage between two points—one above and one below—while the “base” visually grounds the arrow. In practical design and UI writing, it often signals that something can move up and down, toggle between two positions, or represent alignment/adjustment spanning a range. It is less about a precise “up vs. down” comparison and more about indicating back-and-forth motion or a two-state relationship. Because it includes the base, it can read as more structured or directional than a simple up/down arrow pair.
Common uses
- •UI controls for scroll or adjustment (e.g., move an element up/down)
- •Instructions showing bidirectional movement (e.g., lift and lower)
- •Diagrams to indicate flow or interaction between two levels
- •Form and settings labels for items that can change position vertically
- •Text-based mockups where an up/down action needs a grounded icon
