Suggestion Box

Howdy! So while perusing the Suggestion Box, I stumbled across this little thread. I think it is awesome that Hela is able to flip the wolf as she'd hoped.
However, unless someone stumbled upon this thread like I did, how would he/she ever know this ability to flip emoticons is possible?
I went to the emoticon page but there were only the images and tags, nothing about flipping. I also typed in "flip emoticon" along with several variations, in the search engine under "entire site" and came back empty.
I'm sure others have the same or similar question as Hela, so how can they easily find this info out?
Thanks!
