If a field has a choice list attached to it, the choice list may be activated by double clicking on the field. Once the choice list is displayed, the mouse can be used to select an item from the it. If the choice list has scroll bars attached, the mouse can be used to scroll through the choices with the scroll bars. The choice list window is defined to be MODAL; that is, a selection must be made from the choice list or the user must escape from the choice list before another window can be activated. Clicking outside of the choice list window indicates that the user doesn't want to make a selection and the choice list is removed (as though the user had pressed the Quit key, KEY_ESC).
The user can increase the size of the choice list window, but he or she cannot increase the size of the highlight bar, since it is the information covered by the highlight bar that is copied into the field. The user can shrink a choice list window so that only one item is displayed.
When selecting with the mouse, choice list options are respected. For example, if CLCONFIRM is ON, the user must first activate the choice list item with the mouse, then click on it again to copy that item to the field and remove the choice list window.
