In the first tutorial, I thought I saw a fleeting reference to "sleep" and "snooze" unmoved units. I can't find a reference in the manual. Anybody else notice this?

I presume this refers to the small "zZz" button located right of the purchase button.
Clicking it once removes the unit from the roster of "to me moved" units for this turn, clicking it twice makes it "sleep until awakened" and a little "zZz" animation appears on it.
