The slider both displays and sets a value from a continuous range, such as speed, brightness, or volume. Use TAB or the appropriate access key to move the focus to the slider. HOME or END Selects the lowest or highest setting. PAGE DOWN Selects a somewhat lower or higher setting depending on the application. Spin boxes appear as a text box with up and down arrows used to select from a list of fixed values.
List boxes display a column of available choices.
If there are more choices than can fit in the open list box, moving the selection through the list will cause more choices to scroll into view. Use TAB or type the appropriate access key to move the focus to the list box. Single selection list boxes allow only one item to be selected from the list at a time. Items are selected when navigating to them, and moving to a second item will automatically deselect all other items. Drop-down list boxes show only the selected item.
