Expand or Shrink All Details in Get Info Windows with an Option Click

If you want quickly expand (or minimize) all of the detail sections within a Get Info window, just Option-click a single arrow. Instead of only expanding (or shrinking) that subheader section, all detailed sections will expand or shrink concurrently.
This may be an addition to OS X Lion only, at the least I didn’t know about it before Lion existed.
Update: Apparently it works in Mac OS X 10.6 and earlier as well, thanks to those who pointed this out in the comments.
Update 2: For those unfamiliar with “Get Info” windows, select any item in the Finder and hit Command+i or choose “Get Info” from the file menu. The resulting menu gives you details on the file or application, the ability to change permissions, file type, and more.

it works as far back as Leopard (10.5) for sure, and possibly further, although I’m unsure of that
yep, works fine also on snow leopard !
OK …. it doesn’t work on 10.4, so it’s 10.5 later.
and there’s also the command + option + i
This works in Snow Leopard also……
