Figure 2-15: The Background control here is an example of a list.
To choose an option from a list, click it. If the list has a scroll bar, you can use any of the techniques
described in the next section to scroll through the list and view additional options.
You also can make selections from a list box using the keyboard. Press Tab or Shift+Tab until the focus
(the gray frame) is inside the list box. Then use the up- and down-arrow keys to move the highlighter to
the option you want and press Enter.
Scroll bars
Scroll bars, as mentioned, enable you to scroll through lengthy lists of items. They usually appear to the
right of a lengthy list. However, scroll bars aren’t limited to dialog boxes. They appear any time there’s
more information that can be seen at the moment. In Figure 2-16, for example, I’m viewing the contents
of my My Music folder, using the Windows Explorer program (which isn’t a dialog box at all!). The scroll
bar near the middle of the window is actually attached to the Explorer bar on the left side of the window.
Which tells me that there’s more information below in the Explorer bar.
