Spin buttons

If a text box displays a number, a date, or a time, the text box may have a pair of little spin buttons
attached to it, such as the Wait option in Figure 2-14. Click the up button to increase the number, or the
down button to decrease the number. Optionally, you can just drag the mouse pointer through the
contents of the box, and type in a new number.
Lists
A list or list box is a list of alternative options. It’s similar to a drop-down list, except the list is already
open — you don’t need to click any button to view the list. In Figure 2-15, the Background control
presents a list of backgrounds from which to choose. There are more items in the list than are currently
visible, as indicated by the scroll bar to the right of the list.
