Downwards Arrow with Corner Leftwards

The Downwards Arrow with Corner Leftwards at U+21B5 is a bent arrow symbol that most commonly represents the Return or Enter key action: move down to a new line and back to the left margin. It belongs to the Arrows block, a set of directional and functional arrow signs used in text, notation, and interface labels. Its most familiar use is in keyboard and software documentation, where it labels “press Enter,” “insert a line break,” or “submit this line.” You may see it on older keycaps, setup guides, shortcut lists, or help text such as “type the command, then press ↵.” In word processors and text editors, it can also stand for a paragraph return or hard line break when explaining hidden formatting marks. The symbol sometimes appears in command-line tutorials, chat conventions, and forms to show that input continues after the user confirms a line. It is related in meaning to carriage return and newline concepts, but it is a visible symbol rather than an actual control character. Its shape can be confused with similar return-arrow icons, so its exact appearance may vary between fonts and keyboard legends.
