I got a message from splunk when I signed up for answers, saying something like "add som style for your posts", but I have mislaid this.
It would be nice to have a permanent post with formatting options, syntax help, keyboard shortcuts, rules and recommenadation for the answers site.
But maybe there is such a post but I'm not capable of finding it?
If you click the "help" (question mark") button on the top right of the editors, it takes you to http://answers.splunk.com/editing-help which might be what you're looking for?
Perfect! Just what I was looking for.
