Ok, first, if you ever work with HTML or CSS and you haven’t seen Emmet yet, take a minute and check it out. I’ll wait.
If you haven’t seen Cheaters, it’s my cheat sheet system for all of the code craziness I have to keep track of. There’s a GitHub page for it with instructions for creating the popup cheat sheet system, and I put up a demo that includes Emmet as a preview. As always, if you create any cheat sheets you think would be handy for others, please contribute to the collection. Thanks to everyone who’s pitched in so far!
