jQuery cheat sheets.
UPDATE: Scott has a link to the 1.2 cheat sheets. Link below.
I recently just ran into these and never even knew they existed. Note to John: Put these in the footer of the jQuery site. Here are two links to the jQuery cheat sheet that you can download (PDF Format). In just two sheets, it pretty much covers almost everything you could want to know about the jQuery syntax and chaining methods. I would suggest downloading and printing them out. Then hang them next to your computer like a true jQuery geek!!!
