If you want to use an application that you recently used, instead of hunting for it via the Launch button, you can access the Recent Applications window and quickly access the application from there.
1. Go to the Home screen.
2. Longpress the Home key.
3. The Recent Applications window will appear.
Select the desired application or tap the Back key to exit the window.
