   4b. SUMMARY AREA Commands
       The summary area interactive commands are always available in both full-screen mode and alternate-display mode.  They affect the beginning lines of your display and will determine the position of messages and prompts.

       These commands always impact just the ‘current’ window/field group.  See topic 5. ALTERNATE-DISPLAY Provisions and the ‘g’ interactive command for insight into ‘current’ windows and field groups.

          C  :Show‐scroll‐coordinates toggle
              Toggle an informational message which is displayed whenever the message line is not otherwise being used.  For additional information see topic 5c. SCROLLING a Window.

          l  :Load‐Average/Uptime toggle
              This is also the line containing the program name (possibly an alias) when operating in full-screen mode or the ‘current’ window name when operating in alternate-display mode.

          t  :Task/Cpu‐States toggle
              This command affects from 2 to many summary area lines, depending on the state of the ‘1’, ‘2’ or ‘3’ command toggles and whether or not top is running under true SMP.

              This portion of the summary area is also influenced by the ‘H’ interactive command toggle, as reflected in the total label which shows either Tasks or Threads.

              This command serves as a 4‐way toggle, cycling through these modes:
                  1. detailed percentages by category
                  2. abbreviated user/system and total % + bar graph
                  3. abbreviated user/system and total % + block graph
                  4. turn off task and cpu states display

              When  operating  in  either  of  the  graphic  modes,  the display becomes much more meaningful when individual CPUs or NUMA nodes are also displayed.  See the the ‘1’, ‘2’ and ‘3’ commands below for additional
              information.

          m  :Memory/Swap‐Usage toggle
              This command affects the two summary area lines dealing with physical and virtual memory.

              This command serves as a 4‐way toggle, cycling through these modes:
                  1. detailed percentages by memory type
                  2. abbreviated % used/total available + bar graph
                  3. abbreviated % used/total available + block graph
                  4. turn off memory display

          1  :Single/Separate‐Cpu‐States toggle
              This command affects how the ‘t’ command’s Cpu States portion is shown.  Although this toggle exists primarily to serve massively‐parallel SMP machines, it is not restricted to solely SMP environments.

              When you see ‘%Cpu(s):’ in the summary area, the ‘1’ toggle is On and all cpu information is gathered in a single line.  Otherwise, each cpu is displayed separately as: ‘%Cpu0,  %Cpu1,  ...’   up  to  available
              screen height.

          2  :NUMA‐Nodes/Cpu‐Summary toggle
              This command toggles between the ‘1’ command cpu summary display (only) or a summary display plus the cpu usage statistics for each NUMA Node.  It is only available if a system has the requisite NUMA support.

          3  :Expand‐NUMA‐Node
              You will be invited to enter a number representing a NUMA Node.  Thereafter, a node summary plus the statistics for each cpu in that node will be shown until the ‘1’, ‘2’ or ‘4’ command toggle is pressed.  This
              interactive command is only available if a system has the requisite NUMA support.

          4  :Display‐Multiple‐Elements‐Adjacent toggle
              This command toggle turns the ‘1’ toggle Off and shows multiple CPU and Memory results on each line.  Each successive ‘4’ key adds another CPU until again reverting to separate lines for CPU and Memory results.
