list</title><prolog><metadata><keywords/></metadata></prolog><conbody>

<p>Multi-selection lists are used when the purpose is to emphasize that it

is possible to select several items from a list at the same time. Typically,

there is an on-going operation that expects one or more items as input. An

example of this is when the user is creating a group, and a list of names

is offered as a multi-selection list.</p>

<p>In a multi-selection list, the user can browse the items and check and

uncheck any number of them. The state of each item is indicated in a checkbox

adjacent to the item. When the user accepts the list, information about the

marked items is passed to the application.</p>

<p>Items are checked and unchecked using the Selection key, and the list is

accepted with the left softkey Done/OK. Note that unlike in a markable list,

the Options softkey is not available: one can only check and uncheck items

and then accept or cancel the list.</p>
