Now and then my fingers stray around on the computer keyboard and I end up clicking a few wrong buttons in a row. Most often this just gives me typos – but, now and then I get my keyboard messed up. It types the wrong characters. I can’t type things like @ or ? and other stuff comes up instead. I’m typing the characters which show up in blue on my keyboard, alternate characters, instead.
This is not something which needs to drive you crazy. The fix is simple!
press hold left ctrl+shift and tap right shift key
This works! I don’t remember how I fixed the blue character keyboard problem the last two times I’ve had it happen. But, it was something simple like this. It did not involve changing the keyboard language – but that is the tech support advice which comes up most when you search for help.
I am adding this here hoping it will help someone else. Maybe even me the next time it happens.
