Rightwards Arrow to Bar

Rightwards Arrow to Bar at U+21E5 indicates movement or navigation to a right-hand boundary, stop, or next tab position. It is part of the Arrows block and is a printable symbol rather than a keyboard control, even though it is closely associated with keyboard notation. Its most familiar use is as the Tab key symbol on keyboards, operating-system menus, shortcut lists, and application help pages. In that setting it means “press Tab,” “move to the next field,” or “advance to the next tab stop,” such as in form navigation or spreadsheet cell movement. It also appears in user-interface documentation for focus traversal, indentation, and text editing, where a rightward arrow ending at a vertical bar visually suggests advancing until a boundary is reached. In mathematical or diagrammatic writing it can occasionally be used as a custom arrow meaning maps to an endpoint or moves rightward to a limit, but that use is far less standardized than its keyboard meaning. Because it resembles some tab-key icons and other barred arrows, it is best read from context: in software documentation it nearly always refers to Tab, not a literal right arrow key.
