Contrary to expectation, the TAB key does not trigger a list box's VALID
clause.
CAUSE
Unlike most screen GET objects, in order for its VALID clause to be
executed, a list box requires a selection be made with a press of the ENTER
key or a double-click of the mouse. Even though positioning the highlight
bar on a particular entry in a list box and pressing the TAB key updates
the list-box variable's value, the VALID clause is ignored.
STATUS
This behavior is by design.
