About the slider and keyboard
The slider enables you to use your BlackBerry® smartphone when it's open or closed. For example, when the slider is closed, you can use the touch screen keyboard to type short responses to messages. When the slider is open, the slide-out keyboard is available for you to type longer messages, access keyboard shortcuts, and type while you view a full screen of content. You can also open the slider to answer a call and to turn on backlighting.
You can use the touch screen keyboard in either portrait or landscape view. If you open the slider when the touch screen keyboard is displayed, the touch screen keyboard disappears and the smartphone displays screens in portrait view. Videos are displayed according to your smartphone's orientation.
