How do you type the greek small letter xi on each platform?

|---|---|
| Any device | Click the ξ at the top of this page. It goes straight to your clipboard, and you paste it with Ctrl+V on Windows or Cmd+V on a Mac. This is the only method that behaves identically everywhere. |
| Windows | There is no short alt code for this character. Press Win and the full stop key to open the emoji and symbol panel, then use the symbols tab and search for greek small letter xi. |
| macOS | Add Unicode Hex Input under Keyboard settings, switch to it, then hold Option and type 03BE. Without that input source, open the Character Viewer with Control+Command+Space and search for greek small letter xi. |
| Linux and ChromeOS | Press Ctrl+Shift+U, type 03be, then press Enter or the space bar. This works in GTK applications and with IBus. |
| Microsoft Word | Type 03BE in the document, then press Alt and X together with the cursor immediately after the last digit. Word replaces the digits with ξ. |
| Google Docs | Insert, then Special characters, then paste U+03BE or type greek small letter xi in the search box. You can also draw the shape in the sketch pad on the right. |
| Excel and Google Sheets | Use the formula UNICHAR(958) in a cell. Copy the cell and paste it as a value if you want the character rather than the formula. |
| HTML | Write ξ, or the numeric reference ξ, or ξ. On a page served as UTF-8 the character itself also works. |
| CSS | Use content: "\03BE" inside a ::before or ::after rule. Terminate the escape with a space if the next character is also a hexadecimal digit. |
| JavaScript | The escape \u03BE produces this character inside a string literal, and the same escape is valid in JSON. |
