Scrolling: When there's more text and pictures on a Web page than can fit on the screen you need some way of moving the page up so that you can see what is below. This is called scrolling. You can use the up and down arrow keys or the 'page up' and 'page down' keys on your keyboard to scroll a Web page.

Scroll bar: The rectangular strip that appears on the right edge of a Web page. It has an up arrow at the top, a grey area with a box in it in the middle, and a down arrow at the bottom. You can click on the gray area or the arrows to scroll to the text that is off the screen. Try it and see.

Dragging: Try putting the pointer over the box in the scrollbar and hold down the mouse button while moving the mouse up and down the scroll bar. Moving something this way with the mouse is called dragging.
