+Applied to the first process displayed, these commands will show

+Such data will be displayed in a separate window at the bottom of
+the screen.
+
+Keying the same command a second time removes that separate window
+as does the death of the targeted task.
+Keying a different Ctrl combination, while one is already active,
+immediately transitions to the new information.
+
+Notable among these provisions is the Ctrl+V (environment) command.
