The user is experiencing an issue where typing an Alt-code character causes it to repeat or duplicate unexpectedly when typing subsequent letters.

How to Stop Alt-Code Characters from Repeating in Windows

Product: Windows Keyboard Input
Device & OS: Windows
Scenario: Typing special characters using Alt-code sequences in various desktop applications.
Observed behavior: The Alt-code character reappears instead of the intended keystroke when typing a new letter, such as typing 'a' and getting another 'ó' instead.

Before you start

Before troubleshooting, test typing the exact same Alt-code sequence in a different application, such as Notepad, to determine if the issue is system-wide or isolated to specific software.

Solution 1Recommended

Diagnose Windows Keyboard Layout and Accessibility Settings

Determine if the issue stems from conflicting keyboard layouts or accessibility settings like Sticky Keys.

Sometimes, Windows accessibility settings or language layouts can interfere with how Alt-codes are processed, causing the modifier key to act as if it is still being held down.

Disable Sticky Keys

Press the Windows key, type 'Ease of Access keyboard settings', and press Enter. Ensure that the toggle for 'Use Sticky Keys' is turned off.

Check Keyboard Layout

Click the language indicator on your Windows Taskbar (e.g., ENG). Make sure the correct standard keyboard layout is selected, rather than an alternate configuration that might alter keystroke behaviors.

Perform a Hardware Test

Unplug your current keyboard and plug in a different one. Test the Alt-code sequence to rule out a physically stuck Alt key.

Alternative Input: If you are using a laptop without a dedicated numeric keypad, Alt-codes may behave unpredictably. Ensure NumLock is enabled if using a secondary keypad.

Solution 2

Isolate the Specific Application Causing the Issue

Check if a specific program's auto-correct or macro settings are mishandling Alt-code inputs.

Frequently Asked Questions

Why is my Alt key acting like it's continuously pressed?

This typically happens if 'Sticky Keys' is enabled in your Windows Ease of Access settings, which allows modifier keys to remain active without holding them down. It can also be caused by physical dirt or debris stuck under the Alt key.

Do Alt codes work on laptops without a numeric keypad?

Standard Alt codes require a dedicated numeric keypad to function properly. On laptops without one, you may need to use an 'Fn' key combination along with secondary number keys, or use the Windows Character Map app instead.

How do I fix a keyboard that types the wrong accented characters?

Check your Windows Language and Region settings. Ensure that your selected software keyboard layout matches your physical keyboard. If it is set to 'US International', certain keys like the apostrophe will act as dead keys to create accents, which changes normal typing behavior.
