Abstract: A technique for controlling a touch screen device to select an element from a first list using a second list of numbers assigned to each element in the first list. When displayed next to each other, the first and second lists have different respective spacings between their elements. The spacing used in the second list is scaled so all the numbers therein can fit on the display. In operation, the display is touched at an initial touch point. Dragging the finger up the display will pull up the second list at the touch point, while simultaneously pulling up the first list next to it. However, since the spacing is different for each list, the first list can scroll faster and farther than the second list. The entire second list can fit on the display, but the first list scrolls beyond the display limits. The element corresponding to the number under the touch point is highlighted.

Abstract: A method and apparatus includes a user interface of a computing device for diagonal scrolling in a two-step selection process. The method includes presenting a main list and a sub-list substantially orthogonal to the main list, wherein the sub-list comprises elements associated with each element in the main list; receiving user input from a user to progress through the main list and/or the sub-list; and scrolling through the main list and/or the sub-list simultaneously responsive to the user input, wherein the main list and the sub-list are simultaneously scrolled responsive to a diagonal scrolling gesture as the user input.
