A scroll bar appears when content exceeds the visible display area. To scroll, place and hold your finger within the scrollable area, then drag it up or down. Dragging your finger more rapidly increases the scrolling speed. Scrolling can also be performed by turning the Inner DCK when the cursor is present inside the scrollable content. Some windows provide tabs grouping multiple categories of information or buttons. Touch the desired tab to display its contents and manage settings or information. The selected tab is highlighted in blue.
