Unlike in Google Groups, and many other places on the web, we can use markdown here. For example:
A quote
> hello world!
asdafafsf
Bold
**hello world!**
hello world!
Italics
*hello world!*
hello world!
Code
`print(“hello world”)`
print("hello world")
That’s just a few things. I’m not positive what all syntax this editor supports, but see here Daring Fireball: Markdown Syntax Documentation for help on syntax.
