As you move through the list, the slider will move close to the selected arrow. The slider shows which section of the list is currently displayed in the list box. You can also use the slider to move through the list by dragging the mouse cursor on the slider to the desired location between the arrows. You can select an item by clicking on it. Double clicking on an item performs the same function as clicking once on the item and then clicking on the OK button.
Check boxes represent a series of options that can be selected in any combination.
To select a check box, simply click the left mouse button on the check box. The same procedure can be followed to deselect a check box. Radio buttons represent a group of choices for which only one option from the group can be selected at any given time. To select an option represented by a radio button, click the left mouse button on the desired radio button. Any other radio buttons in that group will automatically be deselected.
