Meaning & usage
Double up arrow (⇑) indicates a direction, a transition or the next step in text.
Its orientation matters: choose a matching arrow for navigation hints, comparisons or a sequence of steps.
The double up arrow points toward upward with a double-line shaft; U+21D1 distinguishes it from other arrows that can look similar at small sizes.
double up arrow occupies one Unicode code point. A similar-looking letter, punctuation mark or emoji is not necessarily interchangeable with ⇑ in search, filenames or text processing.
How to type double up arrow
- Windows
- Use Win + . for the emoji and symbol panel, or Character Map for supported fonts. In Microsoft Word, enter each hexadecimal code (21D1) and press Alt + X. There is no universal decimal Alt code for this character; legacy Alt codes depend on the code page.
- Mac
- Open Character Viewer with Control + Command + Space and search for double up arrow. With the Unicode Hex Input keyboard enabled, hold Option and enter the UTF-16 units shown above. Standard Option shortcuts do not cover every Unicode symbol.
- Linux
- In compatible GTK applications, press Ctrl + Shift + U, enter 21D1, then Enter. Enter each code point separately for sequences. Other desktops or apps may require their character picker.
- iPhone & Android
- Look for double up arrow in your emoji keyboard if available, or copy it here and paste. Save frequently used symbols as a text replacement or keyboard shortcut; availability varies by keyboard.
