From S60 3rd Edition, Feature Pack 2 onwards, S60 includes the Application Interworking (AIW) framework feature. Application Interworking is used to dynamically add features and functionality to applications without (static) linking to the existing code, and without knowing in advance which services are available in the device.
The AIW framework also allows you to attach context sensitive help menus in the S60 platform to your application using the Help AIW Provider. The AIW framework handles the dynamic addition of these functions to your application.
For more information on how to attach your help application to the AIW framework, see Adding context sensitive help to your application menu.
For information on how to switch the "show open applications" option off and on, see Switching the "show open applications" option off and on.
