Yes. It's a modification of markdown. Some syntax is the same, but there are a few differences. Text surrounded by asterisks (*) is italicized.
Text surrounded by plus signs (+) is bolded.
Text surrounded by vertical bars (|) is quoted. If you double-click a paragraph, it will be quoted.
Text surrounded by tildes (~) is blocked out.
Symbols such as *, +, |, and ~ can be used literally by placed a \ in front of the text.
A user's name surrounded by at signs (@) links to their profile, and the user is notified that you mentioned them.
A word surrounded by hash signs (#) becomes a tag and links to posts with that tag.
Blank lines separate paragraphs.
Text after a blank line that is indented by two or more spaces is reproduced verbatim in a different font.
URLs become links.
Text can link to URLs by using the following format: /linked text
That was not easy to do. Image URLs (.png, .tif, and .jpg) will embed automatically.
Yo. As someone who didn't really use reddit to much, some of this is a bit confusing to me. If I want to make certain text link to a certain website, I gather from this that i would to the / before the text thing. My question is, where does the link go? As in, how does it know where to link the text to? Furthermore, does imputing a link to a video automatically paste that link as the video itself in the post?
