You can use the Control-C keyboard shortcut at any time within a subcommand to immediately exit 
return to the top level of the CLI.

The CLI keeps a history of all commands you type during a session. Use the Up and Down arrow keys 
on your keyboard, or the Control-P and Control-N key combinations, to scroll through a running list of 
the recently-used commands. 

The command-line interface supports command completion. You can type the first few letters of some 
commands followed by the Tab key, and the CLI completes the string for unique commands. If the letters 
you entered are not unique among commands, the CLI “narrows” the set. For example:

For both the history and file completion features of the CLI, you must type Enter or Return to invoke the 
command. 

You can make configuration changes while email operations proceed normally. 

Configuration changes will not take effect until you complete the following steps:

Issue the 

commit

 command at the command prompt.

Give the 

commit

 command the input required.

Receive confirmation of the 

commit

 procedure at the CLI.

Changes to configuration that have not been committed will be recorded but not put into effect until the 

commit

 command is run.
