Arguments: list-widget index &optional off-p
Changes the selection status of list-widget's item at the given index. If off-p is true the item will be deselected; otherwise it will be selected.
Returns nil if an error occurs, otherwise
returns true.
If list-widget is a multi-item-list and the index that
is passed is -1, then all of the items are deselected if
off-p is true and are selected if
off-p is nil. off-p defaults to nil.
list-widget can be a single-item-list, a multi-item-list, or a
combo-box.
