Do you use the Microsoft Edge browser?
There should be three black dots in the upper right corner of your screen.
Click on the black dots. Scroll down to the extreme bottom to Settings. Click Settings. Find Appearance on the left side of that page. Click Appearance. Scroll all the way down to Fonts.
ctrl +- Yes! I used to know that :(
Instructions for edge browser worked perfectly!
Life is better now.
Thanks to one and all. Have a good day!
