+ After adding the desired options, click on @samp{Save Theme} to save
+the Custom theme. This writes the theme definition to a file
+@file{@var{foo}-theme.el} (where @var{foo} is the theme name you
+supplied), in the directory @file{~/.emacs.d/}. You can specify the
+directory by setting @code{custom-theme-directory}.
+
+ You can view and edit the settings of a previously-defined theme by
+clicking on @samp{Visit Theme} and specifying the theme name. You can
+also import the variables and faces that you have set using Customize
+by visiting the ``special'' theme named @samp{user}. This theme, which
+records all the options that you set in the ordinary customization
+buffer, is always enabled, and always takes precedence over all other
+enabled Custom themes. Additionally, the @samp{user} theme is
+recorded in your @file{.emacs} file, rather than a
+@file{user-theme.el} file.
+
+@vindex custom-enabled-themes
+ Once you have defined a Custom theme, you can use it by customizing
+the variable @code{custom-enabled-themes}. This is a list of Custom
+themes that are @dfn{enabled}, or put into effect. If you set
+@code{custom-enabled-themes} using the Customize interface, the theme
+definitions are automatically loaded from the theme files, if they
+aren't already. If you save the value of @code{custom-enabled-themes}
+for future Emacs sessions, those Custom themes will be enabled
+whenever Emacs is started up.
+
+ If two enabled themes specify different values for an option, the
+theme occurring earlier in @code{custom-enabled-themes} takes effect.
