The ZOOMABLE command enables the user to temporarily expand the size of a list box in order to more easily enter or see large blocks of text. The most common places to add this command would be in a process definition, where minispecs are usually entered, or the description property of an entity, where foreign key information tends to be fairly long.
The ZOOMABLE command adds a small button to the right-hand corner of the list box. The button has a plus sign in it when the box is not zoomed, and a minus sign when it is zoomed.
The effect of the command is shown in the two pictures below. The top picture shows the minispec area in its usual, non-expanded state; in the bottom picture, the list box expands to cover the entire dialog page.
