Hi, alone this information doesn't really merit a document, but if part of a compilation of such tips & tricks, it could be very useful. I would like to encourage you to put something together like that, and we can help highlight it on the site. Or you can collaborate with others to create such a document (or plop it into an existing document). How about it?
