Characters that change post formatting

[Biscuit]

I discovered that placing = on the line after text makes it a heading, which is handy.

I also noticed that ~~~ causes formatting changes, but I’m not sure what.

Is there a list of all of these characters which impact formatting of a post?

See http://commonmark.org/help and the tutorial there.

Since that overview doesn’t mention ~~~: These build fenced code blocks, which can also be started by three backticks (```) as mentioned in the help page

Thanks both. I typed in ~~~ and saw some characters appear in colour.

I thought there must be a way to use coloured fonts after all.

But, from your responses, I now realise it was colouring code commands.
