Ctrl Up Arrow  (See Browsing 1 and 2 in this Help system)	

         Press the Ctrl key and Up Arrow simultaneously to 
         display the preceding document in the database, i.e., 
         a document with a Doc ID # immediately preceding the 
         active document.  For example, if the active document 
         has Doc ID #2550, the Ctrl and Up Arrow keys moves you 
         to Doc ID #2549.
