Figure 2-16: Scroll bars in this window indicate that’s there more than can be seen at the moment.
Vertical and horizontal scroll bars in the right pane tell me that there are more icons to view both below,
and to the right, which I can scroll into view. All scroll bars consist of a slider box, a slider bar, and a
couple of buttons
Figure 2-17: The anatomy of a scroll bar
The size of the slider box relative to the size of the slider bar gives you a sense of how much additional
information is available. If the slider box is about 10 percent of the size of the slider bar, about 90
percent of the available information is currently scrolled out of view. You can use any of the following
techniques to scroll through the additional information:
To move up or down a little bit at a time, click the up- or down-arrow button at the end of the
taskbar.
To move more quickly than that, drag the slider box through the slider bar.
To jump to a specific part of the list, click within the slider bar at about where you want to
position the slider box.
If your mouse has a wheel, you may be able to scroll vertically by spinning the mouse
wheel. (I say may be able to, because the wheel doesn’t work in all programs.)
Tip If your wheel doesn’t work right off the bat, click the scroll bar, or just to the left of
the scroll bar. Then try again. It might work this time.
If your hands are super-glued to the keyboard and don’t want to use the mouse, you can use the
Page Up (PgUP), ˇ Page Down (PgDn) keys to scroll vertically. To jump to the top of the list, press the
Home key. To jump to the end of the list, press the End key. If a horizontal scroll bar is available as well,
you can use the ‹ and › keys to scroll left and right.
Text boxes
Text boxes appear wherever you need to type in some information. Before you can type in a text box,
however, the blinking cursor needs to be in the text box. To move the cursor into the text box, just click
the text box. Alternatively, press the Tab or Shift+Tab keys to move through the available controls until
the cursor lands in the text box. Then start typing.
