multiple_select

Multiple Select.

This attribute specifies whether multiple items in a 'list_box' can be selected
(and highlighted) at the same time. Possible values are true or false.
Default : false.
The method of selected multiple items is platform dependent. (On Windows you hold down the 'Ctrl' or 'Shift' key whilst selecting.)
