2. Press and hold the Alt key (either left or right Alt).
3. While holding Alt, type the code 237 on the separate numeric keypad on the right.
4. Release the Alt key. The character φ will appear immediately.

Method 2: Windows Emoji & Symbol Panel

Press Windows + . (period) or Windows + ; (semicolon) to open the native Windows Symbol Palette. Select the Symbols tab (the omega icon Ω), then click φ to insert it into any application.

Method 3: On Laptops Without a Number Pad

If your laptop lacks a dedicated physical numeric keypad, turn on the virtual numeric keypad by pressing Fn + NumLk, or open the On-Screen Keyboard by typing osk in the Windows search bar. Alternatively, click the Copy φ button at the top of this guide.
