This is the information age. Just Google it. I don't meant that flippantly. One of their best features, the Snap Map, is nigh undiscoverable. But after seeing someone else use it and being unable to figure out how to access it, Google was able to tell me. It's absolutely a failure of their UX but say, what's the discoverability of regexps with and without Google? Jira also suffers from the same problem - it's often far easier and far faster to just Google how to do something, rather than figure out eg which particular permissions system you want to be in, in order to be allowed to do a particular action.
