A clamshell or slide type of handheld wireless communication device can include a biasing component to raise or lower a keyboard relative to a first housing of the device. The biasing component can raise the keyboard when the communication device is opened and can lower the keyboard when the communication device is closed. When the keyboard is raised, the keyboard can be flush with or above the first housing or sides of the first housing of the communication device. When the keyboard is lowered, the keyboard can be below the first housing of the communication device.
