How to Fix Alt Codes Not Working in Word and Excel
Question details
The user is unable to insert special characters using Alt codes because the shortcut combinations do not register or they accidentally trigger the Ribbon KeyTips.

- Product
- Microsoft Word, Microsoft Excel
- Device & OS
- not provided
- Scenario
- Attempting to insert special characters, such as the micro symbol, using Alt key and numeric keypad combinations.
- Observed behavior
- Instead of inserting the expected symbol, the Alt key activates Ribbon KeyTips, or the numeric combination fails to produce any output.
Verify that your keyboard has a dedicated numeric keypad. If you are using a laptop without one, locate your Fn key, as it may be required to access the hidden numeric keypad functions.
Enable Num Lock and Enter the Code Quickly
Alt codes require an active Num Lock and must be entered quickly to prevent the Office Ribbon from intercepting the Alt key.
Starting with Office 2007, Microsoft mapped the Alt key to activate Ribbon KeyTips for keyboard navigation. To bypass this and use an Alt code, you must complete the keystroke rapidly using the numeric keypad.
Press the 'Num Lock' key on your keyboard and ensure its indicator light is turned on.
If your laptop requires a function lock for the numeric keys, press 'Fn + Num Lock' or hold the 'Fn' key during the next step.
Press and hold the 'Alt' key, quickly type your desired numeric code (e.g., 0181 for the micro symbol) on the numeric keypad, and release the 'Alt' key.

Use the Built-in Symbol Dialog Box
If keyboard shortcuts continuously fail, you can manually insert any character using the built-in Symbol menu in Word or Excel.
Use WPS Office for Effortless Symbol Insertion
If Alt codes and Ribbon conflicts disrupt your workflow, WPS Office offers an intuitive and seamless way to insert special characters and symbols without the hassle of complex keystrokes.
- 1. Open WPS Office: Launch WPS Writer or WPS Spreadsheet and open your document.
- 2. Go to the Insert Menu: Click on the 'Insert' tab located in the top navigation ribbon.
- 3. Click on Symbol: Select the 'Symbol' option to open the quick access panel or choose 'Custom Symbol' for the full character map.
- 4. Insert Your Character: Find the symbol you need, select it, and click 'Insert' to place it directly into your text.

Frequently Asked Questions
Why does pressing Alt show letters on the top menu instead of inserting a symbol?
In modern Office applications, pressing the Alt key activates Ribbon KeyTips, which are keyboard shortcuts for navigating the menu. To use Alt codes instead, you must hold the Alt key and enter the numeric sequence very quickly before the software shifts focus to the Ribbon.
Can I use Alt codes on a laptop without a dedicated number pad?
Yes, but it requires extra steps. You generally need to activate a secondary numeric keypad mapped to your letter keys (often M, J, K, L, U, I, O) by pressing Num Lock or holding the Fn key along with the Alt key while typing the numbers.
What is the Alt code for the micro symbol?
The standard Alt code for the micro symbol (µ) is Alt + 0181. Ensure you are using the numeric keypad to type the digits, as the number row at the top of your keyboard will not work for Alt codes.
