      entered within the left hand navigation area. 
      This pattern is searched for in the Node,
      Group and Event column.

      may be selected using the from: and
      to: input boxes of the left hand navigation
      area. 
      Its also possible to define a time range ending now by using
      the  pull-down menu.
