'(emacs)Init Syntax' customizable minor mode variables

[YE]

Hello,

Could someone provide an example(s) for the "customizable minor mode
variables" that "do special things to enable the mode"?

The full sentence from the `(info "(emacs)Init Syntax")' node:

>    Some customizable minor mode variables do special things to enable
> the mode when you set them with Customize, but ordinary ‘setq’ won’t do
> that; to enable the mode in your init file, call the minor mode command.
