Example : With some software the prefix of a pound-sign / hash / number symbol is significant. We don't want to it to be a hashtag. Here are a couple examples where I've tried to escape text so that it's not processed into hashcodes. The bolded text is processed, the others are not.
This should not be \#hashed.
Can I [#unhash] one or [#more #than #one] words?
While the text as seen does not get turned into a hash link, the syntax I'm using remains. I just want the text displayed, not linked.
