When using the web version, use your mouse to click and drag, or use the mouse wheel to scroll the news page. To magnify the ePaper, you can use the zoom in/zoom-out (+/-) controls on the toolbar. You can also double-click anywhere on the ePaper to increase the size of the paper, and double-click again to return it to normal size.
When using the mobile app, tap and drag to move the page, and use a pinching motion (using your thumb and index finger) to zoom in or zoom out. Pinch in to shrink the paper and pinch out to make the paper larger.
