@davidbisset Reminds me of a conversation I had with the makers of the Vivaldi Browser. They allow Markdown formatting in the browsers' Notes facility. I asked if they could pop a wee guide or cheat-sheet in there to get people started, like a lot of text-input-heavy programs do.

"Oh, it's not up to us to describe Markdown."
"Not even the form of Markdown you've chosen to implement?"
"..."

If you aren't going to cater to users don't expect users to use what you're giving them.
