I was using
$ characters to mean, well, "dollars" in a question on Economics SE and it caused the rendered text to go all screwy. I briefly reviewed the help text but could not zero in on the meaning of that character as markdown. Finally just "escaped" the character with backslash and got on with things.
But what does
$ mean in Markdown? Does it have a special function on all SE sites, or only some? (I've been on Stack Overflow and EL&U for a long time and never run across this problem.)
