Guide to Typing Special Characters and Symbols in Posts

The forum’s text editor natively accepts all special characters and symbols. Because these characters are generated by your computer or mobile device's operating system rather than the web browser, the method to type them depends on the device you are using.

Below are the instructions and shortcut keys for inserting the most common technical and typographic symbols on Windows, Mac, and mobile devices.

1. Windows OS (Alt Code Method)

To use Alt codes, your keyboard must have a separate numeric keypad (usually on the right side), and Num Lock must be turned on.

• Instructions: Hold down the Alt key, type the 4-digit number sequence on the numeric keypad, and then release the Alt key.
• Common Windows Alt Codes:
  • Degree Symbol (°): Hold Alt + type 0176
  • Lowercase Umlaut (ü): Hold Alt + type 0252
  • Uppercase Umlaut (Ü): Hold Alt + type 0220
  • Plus-Minus Sign (±): Hold Alt + type 0177
  • Copyright Symbol (©): Hold Alt + type 0169
  • Registered Trademark (®): Hold Alt + type 0174
  • Trademark (™): Hold Alt + type 0153

(Note: If using a laptop without a dedicated number pad, you can open the Windows Key + . (Period) shortcut to bring up the native emoji and symbol picker panel).

2. macOS (Keyboard Shortcuts)

Mac operating systems utilize the Option key combined with standard letter or number keys to generate symbols.

• Instructions: Press and hold the designated keys simultaneously. For accented letters like the umlaut, press the modifier shortcut first, release it, and then type the base letter.
• Common Mac Shortcuts:
  • Degree Symbol (°): Option + Shift + 8
  • Umlaut (ü): Option + U, then type U
  • Plus-Minus Sign (±): Option + Shift + =
  • Copyright Symbol (©): Option + G
  • Registered Trademark (®): Option + R
  • Trademark (™): Option + 2

(Note: For the umlaut or other accented characters, you can also press and hold the base letter key—such as U—until a visual menu appears on the screen, then select the desired character).

3. Mobile Devices (iOS & Android)

Mobile software keyboards hide special characters behind primary keys to save screen space.

• Accented Letters (ü): Press and hold the base letter (u) until a sub-menu expands. Slide your finger to select ü and release.
• Symbols (°, ±, ©): Tap the numbers/symbols access button (usually labeled 123 or ?123), then press and hold the primary related symbol. For example, to find the degree symbol (°), press and hold the zero key (0).
