The Hints and tips menu has an entry on them that you don't even have to scroll down for, it's an extra 2 inputs (or 1 after the first time you do it in the session), but it's the same thing.

What I'm talking about with the precision placement (shift-alt) doesn't seem to be referenced anywhere in the hints and tips that I can find. I do feel silly suggesting a key combo list when there already was one, though precision placement still doesn't seem to be mentioned anywhere except the tutorial.
