I wasn't sure if I should make a link to this on the front page or not, since I'm not sure if I'm the only one having trouble remembering what all the codes and shortcuts were that you can use on a wiki! :3
So I'll be showing you a page with a list of helpful syntax. You should bookmark it if you think you'll forget some of it or want to go back for reference. :S
Most of the stuff they list here, the Wikia has shortcuts for, but if you wanted to know anyway here you go.
