Instead of "poking" UI components, users interact with content on the screen using gestures. Avoid cluttering the screen with UI components and design your application to take advantage of the available gestures. For example, allow users to zoom into a picture using the spread gesture instead of tapping a button to incrementally zoom in.
The BlackBerry 10 Dev Alpha supports gestures from the device bezel (the frame around the display area of the screen). You don't need to implement these gestures in your application. They are provided automatically.
|Wake up the device|
|Display the inbox|
|Display a virtual keyboard|
|Display an application menu|
If they apply to your application, you can implement the following gestures to allow users to directly manipulate content on the screen.
|Scroll between two items|
|Select one item|
|Select multiple items|
|Peek (view content on a previous screen)|
|Open an action menu (users can open a tab menu by tapping the tab menu button at the bottom left of the screen)|
|Move an item from one place to another|
|Progress through a file (e.g. song or video)|
