Rightwards Arrow Over Leftwards Arrow is used to indicate direction, sequence, or logical flow — common in UI design (navigation), technical diagrams (flowcharts), mathematics (implication and mapping), and instructional writing (step-by-step guides).
Unicode block: Arrows (U+2190–U+21FF). The Arrows block standardizes directional symbols that were previously drawn inconsistently across different fonts and diagram tools, giving software and documents a consistent way to represent direction, flow, and logical implication.
At Unicode code point U+21C4 (decimal 8644), Rightwards Arrow Over Leftwards Arrow is the 53rd of 112 characters cataloged in this category on How To Type Any Symbol. In terms of typing methods, like most characters outside the 0–255 legacy codepage range, it has no dedicated Alt-code or single-key shortcut on Windows or Mac, so copy-paste is the standard, universal method for typing it. Regardless of platform, clicking the copy button above places the exact character on your clipboard, ready to paste into any application that accepts Unicode text.
💡 Good to know: In UI/UX design, arrow direction has strong conventional meaning to users (right = forward/next, left = back) — reversing this convention can confuse users.
