| ### Navigating the Namespace Once you begin expanding the namespace, it can exceed the boundaries of your CDS browser window, even if you enlarge the window. You can use the horizontal and vertical scroll bars and stepping arrows to scroll through the namespace. Dragging the slider up and down the vertical scroll bar on the right side of the display window produces an index window. The index window shows the name where the slider is currently positioned in the namespace. When the index window contains the name that you want to view, release the mouse button to position that name at the top of the CDS browser window. In displays that are larger than the length of the window, scrolling through directory levels can produce a reference line toward the top of the window. The line orients you by showing the full directory path name from the current name to the root. It also indicates that you have scrolled past other parts of the namespace that are no longer displayed. ##
