Left-Right Arrow ↔
Copy & Meaning

A horizontal double-headed arrow — representing bidirectional horizontal movement, horizontal scaling, and flexibility to move both left and right. This arrow indicates that something spans or can move across the full horizontal range. In interface design, it appears on horizontal resize handles.

'Back and forth' describes the horizontal oscillation that this arrow visualizes. Comparison contexts (comparing option A on the left to option B on the right) use this arrow to indicate the relationship spans both directions. Used for horizontal scroll indication, horizontal resize controls, comparison and contrast visualization, the full range of horizontal positions, and bidirectional movement capability in the horizontal dimension.
