For example, when posting here. I have several paragraphs of text, yet want to
scroll up to correct something. *If I use a finger or stylus, the page scrolls,
not the text within the box. *How...?
It takes a little practice, since two fingers also do the pinch/zoom thing. What works best (for me) is to let your two fingers touch lightly while trying to scroll. Both finger must be inside the box, which can get a bit tricky, so sometimes zooming in first helps.
