A tab-based collapsible user interface includes selectable user interface tabs, a ribbon area, and an editing surface. When a browse tab is selected, the ribbon area displays information and does not include any user interface controls for performing commands. When the browse tab is selected, a vertical scroll bar is displayed adjacent to the ribbon area and the editing surface. When the vertical scroll bar is used, the ribbon area and the editing surface are both scrolled. When a page tab or a contextual tab is selected, the ribbon area displays user interface controls for performing commands. When a page tab or a contextual tab is selected, a vertical scroll bar is displayed adjacent to the editing surface but not adjacent to the ribbon area. When the vertical scroll bar is used, the contents of the editing surface are scrolled but the ribbon area is not scrolled. |
