To reset keyboard settings on your Mac, start by navigating to the “System Preferences” menu and selecting “Keyboard.” There, you can explore options such as “Modifier Keys” to reset any custom changes that might interfere with normal operation. If you’ve made adjustments to key repeat or delay settings, restoring these to their default values can also help resolve issues.
Another option is to remove any custom keyboard shortcuts that may be conflicting with the function of the arrow keys. Remember to restart your Mac after making these changes to ensure they take effect. This can often remedy problems and restore functionality to your keyboard.
What should I do if the arrow keys are physically stuck?
If your arrow keys are physically stuck, the first step is to carefully inspect the keys and the surrounding area for any debris or obstructions. Use compressed air to blow out dust and particles that may be lodged underneath the keys. If necessary, you can gently pry off the keycaps, being cautious not to damage the mechanism underneath, and clean the area with a soft, lint-free cloth.
Once the keys are clear, securely press the keycaps back into place to ensure proper function.
