How to Fix Keyboard Typing Wrong Characters

Why This Isn't Just Annoying — It's Productivity Murder
You're typing an urgent email to your boss. You press A — "é" appears. You press Q — "@" pops up. You press M — "0" shows up.
You look insane. Every word is gibberish. Delete, retype, delete again. What should take 2 minutes takes 20. Your face turns red on the Zoom call.
I've lived this nightmare. Mid-client presentation, I typed "Hello team" and it came out as "t飣º †éam". Five people staring at my screen share. The silence was deafening. Client asked if I was okay.
Another time, a freelancer I helped lost a $3,000 contract because his keyboard typed "£" instead of "#" in technical documentation. The client thought he was unprofessional and went with someone else.
Here's what saved me and thousands of others: 99% of "keyboard typing wrong characters" issues are caused by software settings, not broken hardware. And they're fixable in under 5 minutes.
