@Yeferson it sounds like you turned on caret browsing. This is something that has been around since 2000 if not earlier, on pretty much all web browsers.
F7 is the toggle. If you’re not familiar with it, this moves the text cursor, otherwise known as the caret, letter by a letter throughout a page. When you were saying it’s not scrolling, it most likely is but it’s doing it character by character instead of the whole page like you’re used to.
Anyway, press F7 and it should disable it. Or you can go into settings, to accessibility, and make sure the toggle is off there.
It basically exists to allow people to be able to navigate without a mouse. It’s how you scroll across or do anything on a webpage with a keyboard only.
