A narrow mode navigation pane is provided that may be selectively displayed as a replacement of a normal mode or full-size navigation pane to allow more display space for other user interface content. The narrow mode navigation pane is divided into sections, each section including selectable controls for providing data or functionality previously displayed in and selectable from the normal mode navigation pane. Selection of a "Navigation Pane" control causes the temporary display of a pop-up version of the normal mode navigation pane for allowing a user to view and/or select the full contents of the normal size navigation pane without toggling to the normal mode navigation pane. Additional sections of the narrow mode navigation pane may include selectable controls representing a subset of controls from the normal mode pane and for launching other software applications and associated user interfaces.
