When editing the body of a question, "How to Format" has
► put returns between paragraphs
► for linebreak add 2 spaces at end
► _italic_ or **bold**
► indent code by 4 spaces
► backtick escapes `like_so_`
► and some other stuff
► please do not ask how to parse XHTML with regular expressions
► or why two floating point numbers aren't equal
Some questions on Stack Overflow by new users have bold used when backticks should be used instead. If the order of bullet points were changed, they might be more likely to use the correct formatting.
