the user can enter BlackBerry Hub immediately. Devices with a hardware keyboard can use keyboard shortcuts to reach applications or perform specific functions more quickly. Multitasking When a user returns to the home screen from within an application, the application is minimized into a so-called "Active Frame". An Active Frame is a miniaturized window of the application that keeps running in the background. A user can return to such an application by tapping on the Active Frame or close it by tapping on the X icon. Active Frames can have widget-like functionality and show small bits of information, similar to widgets on Android. For instance, the calendar application can show upcoming events and meetings. BlackBerry 10 limits the number of active applications and it varies per device. BlackBerry Hub BlackBerry 10 collates emails, SMS/MMS, calls and notifications into the BlackBerry Hub. It shows all messages and notifications in a continuous list, sorted by date. The user can filter results by application or, in the case of email, also by inbox. The user can create, view or act upon messages or notifications directly from the Hub. For instance, when the user opens a Facebook message, the Hub will open a small part of the Facebook application and allow the user to perform the same actions as the Facebook application itself. Applications need to support the Hub specifically to use most of these features, which is only possible for applications written with the native SDK. Notifications from unsupported applications are collated in the generic notifications tab.
