instructions indicate, you navigate among the fields with the Up and Down arrow keys.  The PgUp, PgDn, Home and End keys can also be used to quickly reach the first or last available field.

           •  The Right arrow key selects a field for repositioning and the Left arrow key or the <Enter> key commits that field’s placement.

           •  The ‘d’ key or the <Space> bar toggles a field’s display status, and thus the presence or absence of the asterisk.

           •  The ‘s’ key designates a field as the sort field.  See topic 4c. TASK AREA Commands, SORTING for additional information regarding your selection of a sort field.

           •  The ‘a’ and ‘w’ keys can be used to cycle through all available windows and the ‘q’ or <Esc> keys exit Fields Management.

       The  Fields Management screen can also be used to change the ‘current’ window/field group in either full-screen mode or alternate-display mode.  Whatever was targeted when ‘q’ or <Esc> was pressed will be made current
       as you return to the top display.  See topic 5. ALTERNATE-DISPLAY Provisions and the ‘g’ interactive command for insight into ‘current’ windows and field groups.

       Note: Any window that has been scrolled horizontally will be reset if any field changes are made via the Fields Management screen.  Any vertical scrolled position,  however,  will  not  be  affected.   See  topic  5c.
       SCROLLING a Window for additional information regarding vertical and horizontal scrolling.

   4a. GLOBAL Commands
       The global interactive commands are always available in both full-screen mode and alternate-display mode.  However, some of these interactive commands are not available when running in Secure mode.

       If you wish to know in advance whether or not your top has been secured, simply ask for help and view the system summary on the second line.

         <Enter> or <Space>  :Refresh‐Display
              These commands awaken top and following receipt of any input the entire display will be repainted.  They also force an update of any hotplugged cpu or physical memory changes.

              Use either of these keys if you have a large delay interval and wish to see current status,

          ? | h  :Help
              There are two help levels available.  The first will provide a reminder of all the basic interactive commands.  If top is secured, that screen will be abbreviated.

              Typing ‘h’ or ‘?’ on that help screen will take you to help for those interactive commands applicable to alternate-display mode.

          =  :Exit‐Display‐Limits
              Removes  restrictions  on what is shown.  This command will reverse any ‘i’ (idle tasks), ‘n’ (max tasks), ‘v’ (hide children) and ‘F’ focus commands that might be active.  It also provides for an exit from PID
              monitoring, User filtering, Other filtering, Locate processing and Combine Cpus mode.
