 * Optional monitored processes list (new in 1.7)
 * Processes list
 
+The processes summary line display:

+* Tasks number (total number of processes)
+* Threads number 
+* Running tasks number
+* Sleeping tasks number
+* Other tasks number (not running or sleeping)

 By default, or if you hit the ``a`` key, the processes list is automatically
 sorted by CPU of memory usage.
