The Symbian UI style allows multitasking; that is, working with more than -one application simultaneously. Mobile device users can leave an application -running when they start another application, swap between running applications, -and interact with them.

-

To open a new application without closing the one that is presently being -used, users can press the Home / Menu key to go to the Menu and -select application suites and applications.

-

The first application process remains running in the background while the -user interacts with the second application.

-

The task swapping window displays the applications that are currently running -in the order of their most recent use. By default, the focus is on the first -item in the grid. The task swapping window is a pop-up with a heading (Open -applications). The names of the open applications are displayed -in an Information pop-up. The Information pop-up is launched with a 0.5 second -delay after the focus is moved onto each item, and it remains visible for -1.5 seconds (or until the focus is moved to another item). Menu and home screen -are always visible in the task swapping window. The configuration and visual -appearance of the task swapping window might depend on the product.

-

Users can use the task swapping window to close active applications. In -devices with a keypad, users move the focus onto the application to be closed, -and press the Clear (delete) key. In touch devices, -users tap and hold the item to open a pop-up menu where they can select the Exit option.

For implementation information on -using the application -and UI frameworks, see Window -server events.
