Rework the master CLI section the same way the "Unix Socket commands"
section is made, ordering the available keywords in the section.

+@<[!]pid>
+  The master CLI uses a special prefix notation to access the multiple
+  processes. This notation is easily identifiable as it begins by a @.
 
+  A @ prefix can be followed by a relative process number or by an exclamation
+  point and a PID. (e.g. @1 or @!1271). A @ alone could be use to specify the
+  master. Leaving processes are only accessible with the PID as relative process
+  number are only usable with the current processes.
 
-In this example, the master has been reloaded 5 times but one of the old
-worker is still running and survived 3 reloads. You could access the CLI of
-this worker to understand what's going on.
-
-When the prompt is enabled (via the "prompt" command), the context the CLI is
-working on is displayed in the prompt. The master is identified by the "master"
-string, and other processes are identified with their PID. In case the last
-reload failed, the master prompt will be changed to "master[ReloadFailed]>" so
-that it becomes visible that the process is still running on the previous
-configuration and that the new configuration is not operational.
