Most configuration commands have an undo form for canceling a configuration, restoring the default, or

disabling a feature. For example, the info-center enable command enables the information center, and

the undo info-center enable command disables the information center.

Entering a command

When you enter a command, you can use keys or hotkeys to edit the command line, or use abbreviated

keywords or keyword aliases.
