Typographic Manuals by type.today

While designing a bit of UI, I was trying to find out how to type the interpunct symbol (·) on a Mac (alt + shift + 9), and found this fun, geeky little resource by type.today. They have a few different manuals up on the site that go into typographic details on things like quotation marks, spaces, dashes, brackets, and other characters you may not know a lot about. If you like type, this is a fun read.
