I am asking on behalf of a very elderly friend - he is viewing IE as normal. He wants to read a document to do with banking, but it is several pages long, and to click on next page means scrolling side to side to see everything on the page. He would like to be able to read all without scrolling.
He could use the arrows on his keyboard to do the scrolling (side to side or up and down), that is far easier than dragging with the mouse. I'm guessing that he has magnified the page to make the text bigger to read and that has meant the page is now too wide to fit on the screen.
