In this video we continue in the Post Editor, with Tabs, Spaces, BlockQuotes, Block Indents, Numbered Lists (Ordered Lists, in HTML parlance), Bullet Lists (Unordered Lists), and Undo/Redo. There’s also a quick look at full-screen editing, and a couple other stray buttons and menus.
Hover over the video as it is playing to control volume, etc. You can click the “Full Screen” icon while the video is playing, to see a full screen view which is much easier to follow.
