Woah, I like the translation on this one. How does one do it?
If you open the Edit menu on this page, you'll see the "embed notes" checkbox is selected. That lets the text show up on top of the post without having to hover your mouse cursor over it.
There are three links to "about:" pages in help:notes describing embedded notes in more detail, as well as other kinds of note formatting. If you hover your cursor over a note and click "click to edit," you can see what text was input to format the notes.
Note that you might not be able to do some of these things on mobile devices.
