I'm not sure if it's exactly the same features but I've had success with https://simplemde.com for rich Markdown entry on the web.

I like that it's usable by people who want to click buttons -- and that by showing users both the formatting and the Markdown that caused it, it teaches how to skip the buttons in the future. At the same time, if you're a Markdown user doing everything on the keyboard, it's completely unobtrusive. Everybody wins.
