A method of navigating between different tabs in a user interface of a portable digital information device includes displaying a first set of tabs sequentially arranged along a linear direction on a display of the portable digital information device, the first set of tabs containing tabs that are a subset of tabs contained in a master set of tabs. A user then touches a touch-sensitive area of the portable digital information device and drags a finger across the touch-sensitive area in a direction parallel to the linear direction in which the first set of tabs are sequentially arranged. This dragging motion causes the position of the tabs displayed along the linear direction of the display to move in a direction opposite to the direction along which the user drags the finger across the touch-sensitive area for displaying a second set of tabs containing tabs.
