Scrolling
The technique of moving the window around a large file is called scrolling. You move
the window frame over the file, but because the window actually stays in the same
position on the screen, it appears as though the file is scrolling past the window.
This is not as complicated as it sounds. Try out the techniques on the following
pages, and you'll soon get used to moving around large files.
Most windows have scroll bars and scroll arrows to enable you to move around a file:
Scroll bars
The scroll bars allow you to scroll the window over the file, directory or picture you
are viewing.
Slider
The slider size shows what proportion of the file is visible: if the slider occupies half
the length of the scroll bar, half the file is visible. To display a different area of the file,
drag the slider along the scroll bar. This technique is useful for moving quickly around
a large file.
Scroll arrows
The scroll arrows are at each end of the scroll bar. Click on the arrow showing the
direction you want to move the window in — left, right, up or down. This technique
allows you a finer control over scrolling than dragging the slider.
Some windows (like the one above) only have vertical scroll bars, sliders and scroll
arrows. Others have both vertical and horizontal scroll bars.
