However, software modules that several applications can use (such as editors)
may run simultaneously in more than one application. The user may thus see the
same feature being run in several different applications at the same time.

Opening and closing applications
Applications are typically opened using the Application shell, the menu containing all
installed applications.
There may be other ways to open an application, such as:
Assigning a shortcut to an application into a softkey, to be used in Idle state.
Using a link in Pinboard (see section Pinboard).
Using a specific shortcut built in to another application.
When there is no instance of the opened application already running, a new process
for the application is created. If the application is already running, opening the
application means bringing the existing application process on top. In case of a link
that points to a specific state in an application, the existing application is
interrupted and forced into the target state. See section Multitasking for more
information on this.
The user can close applications in the following ways:
Using the right softkey, which goes backwards in the application hierarchy
(Back) and finally exits the application (Exit).
Using the Exit function in the Options menu.
Closing an application means that the processes associated with it in the working
memory are terminated.
Application processes can also be terminated by the system, for example when the
user powers down the device.
Multitasking
The Series 60 UI style allows multitasking, that is, working with more than one
application simultaneously. To accomplish this, an application can be left running
when switching to another application, and it is possible to swap between running
applications and interact with them.
To open another application without terminating the current one, the user can press
the Applications key to go directly into the Application shell, and select the other
application from there. The first application process then remains running in the
background while the user is interacting with the second application.
It is possible to swap between two or more running applications by using the
Application shell.
