undo Form of a Command
Adding the keyword undo can form an undo command. Almost every configuration command has the
undo form. undo commands are generally used to restore the system default, disable a function or
cancel a configuration. For example, the info-center enable command is used to enable the
information center, while the undo info-center enable command is used to disable the information
center. (By default, the information center is enabled.)
