DISPLAY REGION SCROLLING

Methods and apparatus provide for a Region Scroller. The Region Scroller renders a view of at least a portion of a set of headers, where each header is associated with a respective, expandable-collapsible (E-C) display region The Region Scroller identifies a newly-selected header based on an extent of directional input and modifies the view to include concurrent presentation of (i) the newly-selected header and (ii) an E-C display region in an expanded state, where the E-C display region is associated with the newly-selected header.
