When I open an internet page and start scrolling using my up and down arrow keys on the keyboard the page goes up and down just fine. The problem comes when I click somewhere on the page and suddenly using the up and down arrows on the keyboard is like scrolling up and down the text, like in a word document. The cursor is suddenly scrolling through the text on the internet page instead of scrolling up and down the page as a whole. Or it just goes straight to the bottom of the page and then I am not able to use the arrow keys to go anywhere else on the page.
