Landscape Values

I haven't tried this myself yet but....
In one of the sample projects they have a values-land folder in which there is a dimens.xml file. So I'm assuming that I can move the specific dimensions out into that folder where they'll be picked up automagically in landscape mode.
At the moment I use things like "amount_width_portrait" and "amount_width_landscape" then modify the layout-land to suit.
I wonder if the same applies to drawables-land and menus-land?
