Good resource. In case anyone from PragmaticWorks is reading this - the PDF says "Copy and paste from PragmaticWorks.com/cheatsheet" yet it would be far more handy to have this as text in the PDF. It might even reduce the size of the PDF. Of course, it would reduce the need to visit your site (of save the HTML page).
