:none

No selection is possible.

:single

Zero or one element may be selected.

:browse

Exactly one element is selected. In some circumstances, such as initially or during a search operation, it is possible for no element to be selected with the :browse value. What is really enforced is that the user cannot deselect a currently selected element except by selecting another element.

:multiple

Any number of elements may be selected. The Ctrl key may be used to enlarge the selection, and the Shift key to select between the focus and the child pointed to. Some widgets may also allow Click-drag to select a range of elements.
