Very nice. I tend to steer clear of cheat sheets for Vim etc. as I try to program my motor memory fairly strictly (and use a look-up of the in-depth help system as both punishment and useful exploration). But when switching between languages frequently, or when knowledge of one is getting a little rusty, something like this is just perfect. (I'll also take this chance to recommend 'Programming in Lua' by the creator - Roberto Ierusalimschy. It's really one the clearest, well-paced language texts I've read.)
