Alt Keys and Alt Codes: Unlock Special Characters Easily

Have you ever noticed the Alt key sitting on your keyboard and wondered what it could really do? For most users, the Alt keys are a mysterious part of their keyboard, but in reality, they unlock a treasure trove of functionality—particularly when it comes to creating special Alt characters.

This comprehensive guide explores everything you need to know about Alt code characters: how they work, how to use them, and why they matter. Whether you’re typing professional documents, posting on social media, or designing content, this tool is a must-know skill in your digital toolkit.

What Are Alt Characters and Alt Codes?

Alt codes are numeric shortcuts that produce special characters or symbols when entered using the Alt key and the numeric keypad. These symbols include accented letters (like é), currency symbols (¥, €), punctuation (©, ™), arrows (→, ↑), and even Greek letters (π, Ω).

The magic happens when you hold down the Alt key and type a specific sequence of numbers on your numeric keypad, called Alt codes. For example:

• Pressing Alt + 0169 gives you the © symbol.
• Pressing Alt + 0176 types the ° symbol (perfect for weather updates or math equations).

How Do Alt Codes Work?

To input an Alt character:

1. Hold down the Alt key.
2. Type a numeric code using your keyboard’s numeric keypad.
3. Release the Alt key.
4. Voilà! The character appears.

Example:

• Alt + 0169 = ©
• Alt + 0176 = °
• Alt + 0216 = Ø

Alt codes use the ASCII (American Standard Code for Information Interchange) and extended character sets from the Unicode system to represent these characters.

How to Use Alt Codes on Your Keyboard

Alt codes are simple to use, but here’s how to do it correctly:

Step-by-Step Instructions

1. Use the Numeric Keypad: These codes work only on the numeric keypad on the right side of your keyboard—not the number row at the top.
2. Enable Num Lock: Make sure your Num Lock is turned on.
3. Hold the Alt Key: Press and hold the Alt key.
4. Type the Code: Enter the Alt code for the character you want.
5. Release the Alt Key: The symbol will appear.

On laptops without a numeric keypad, use the “Fn” key in combination with the embedded keypad.
