‘[+]’. When the group contents are visible, this button changes to
‘[-]’; invoking that hides the group contents.

‘[Option]’ or ‘[Face]’. Invoking this button creates an
ordinary customization buffer showing just that group and its
contents, just that user option, or just that face. This is the way

customize-apropos can only find groups and settings that are
loaded in the current Emacs session. See Customizing Specific Items.
