I saw this on Digg before and thought it may be of use to some people. I am aware that Rob has already posted the SEO cheat sheet and some may have already seen this, but for those that haven't it may help.

 

Web Developer Cheat Sheet

Nice find!

The mootools one is especially useful.

I've just downloaded the entire mootools docs and printed them out for reference but cheat sheets are always useful!

Thanks! Nice for when I forget somthings and i think the wordpress one will help with some future projectss.

Thats absolutely superb. I was looking for something like that!

That's brilliant. It will come in very handy. Thanks for sharing.
