Learn Snippets Randomly

The new Help -> OP Snippets in 2018.20000 had an inspiring Rand button to give you a random snippet. I know some of us like learning this way - just fire me a random technique, and some day I will likely use that knowledge.

The new Snippets works well on macOS now, and a “Newest” button shows recently-added and -edited snippets, as well as a good old Next button to step through the examples with no mouse movement.
