Using Scroll Bar To Navigate Around Documents And Pages

Scrolling: These days, PC monitors are bigger than ever—but so are the Web pages and documents they display. Scroll bars, of course, are the strips that may appear at the right side and/or bottom of a window. The scroll bar signals you that the window isn’t big enough to reveal all of its contents.

Click the arrows at each end of a scroll bar to move slowly through the window, or drag the rectangular handle (the thumb) to move faster. (The position of the thumb in the scroll bar reflects your relative position in the entire window or document.) You can quickly move to a specific part of the window by holding the mouse button down on the scroll bar where you want the thumb to be. The scroll bar rapidly scrolls to the desired location and then stops. 
Scrolling is such a frequently needed skill, though, that all kinds of other scrolling gadgets have cropped up. Your mouse probably has a little wheel on the top. You can scroll in most programs just by turning the wheel with your finger, even if your cursor is nowhere near the scroll bar. You can turbo-scroll by dragging the mouse upward or downward while keeping the wheel pressed down inside the window.

Laptops often have some kind of scrolling gizmo, too. Maybe you have an actual roller, or maybe the trackpad offers draghere to-scroll strips on the right side and across the bottom. And if you have one of the new breed of touchscreen computers, of course, you can scroll just by dragging around with a finger (or two fingers, on multitouch screens).

Of course, keyboard addicts should note that you can scroll without using the mouse at all. Press the Page Up or Page Down keys to scroll the window by one window-full, or use the arrow keys (Up / Down) keys to scroll one line at a time.
