Text cursor showing up on elements of the page causing problems

The text cursor has appeared recently on the page elements, arrow keys behave different now, because instead of moving the page moves the cursor, to move the page you have to move the cursor as in Word. The cursor passes over the elements text, images, icons. The cursor selects the “selectable” elements just as the tab key would do.

Steps to Reproduce:
1.Launch Brave
2.Visit any website, then press up or down arrow key,

Actual Result:
The text cursor will show up in some place, and the page will not move until the cursor reaches the beginning or end of the page.Captura de tela 2020-10-16 225911 Captura de tela 2020-10-16 222158

I found out that is due to the “caret browsing mode”, I probably hit the F7 key, that toggle this mode.
