How To Get Back The Google Cache Function

How to get back the Google Cache function.  I've seen some other ways described, such as a "preview" function that I don't see and arrows that aren't there...suffice it to say, the one below does work.

(Per Google's Guide)

You can also retrieve Google’s cached version of a page via the cache: search operator. For example, [ cache:www.pandemonia.com/flying/ will show Google’s cached version of Flight Diary in which Hamish Reid documents what’s involved in learning how to fly.

On the cached version of a page, Google will highlight terms in your query that appear after the cache: search operator. For example, in the snapshot of the page www.pandemonia.com/flying/, Google highlights the terms “fly” and “diary” in response to the query [ cache:www.pandemonia.com/flying/ fly diary ].

Use the Wayback Machine when you want to visit a version of a web page that is older than Google’s cached version.
