Frequently Asked Questions

Why does the arrow key work in other apps but not in Word on Mac?

This usually indicates a Word-specific software glitch, a corrupted preference file, or an incompatible Word add-in rather than a hardware failure, since the key registers properly in the rest of the macOS environment.

Can a Windows keyboard layout cause arrow key issues on Mac?

Yes. If a third-party external keyboard is stuck in 'Windows' mode, it might send input codes that Microsoft Word for Mac misinterprets. Ensure your keyboard is toggled to the Mac layout if it has a physical switch or dedicated shortcut.

Will reinstalling Microsoft Word fix the arrow key issue?

Reinstalling can resolve deep application corruption, but you should first try moving the 'com.microsoft.Word' preferences folder to the desktop to force Word to rebuild its settings. This fixes most input glitches much faster than a full reinstall.
