It seems that for some people, the A4 one-sided format of the cheat sheets isn't quite suitable. Many prefer a pocket-sized guide they can refer to but keep out of sight (or on their person) unless needed. NoteBind.com have put together a post on compiling a pocket reference, in which they simply print and combine a variety of different cheat sheets and references into one handy, and most importantly pocket-sized, "NotePack" (PDF available from the site).
