How do I unhide a style?

I had the Styles and Formatting panel open and curiously chose to hide a paragraph style. Now I can’t find a list that includes hidden styles to put it back where it belongs. Is there a check box I am not hitting or an option in the Office Launcher that I should be navigating to?

You probably chose to show only the used styles. Select All styles from the list box at the bottom of the styles list.

That drop-down list also features a “Hidden Styles” option. I feel silly for not seeing this before. Thanks for setting me straight.
