Chapter 10 Install and System Administration for FortiOS 5.0 : Using the CLI : Command syntax : Indentation
  
Indentation
Indentation indicates levels of nested commands, which indicate what other subcommittees are available from within the scope. For example, the edit sub-command is available only within a command that affects tables, and the next sub-command is available only from within the edit sub-command:
config system interface
edit port1
set status up
next
end
For information about available sub-commands, see “Sub-commands”.
