After using Word 2003 for years and being accustomed to closing docs using the "x" in the upper rt corner of the doc window, I'm at a loss how to close a Word 2007 doc without having to use the two-step process of clicking on the Office Button, then Close. Unless I'm missing something, I don't see the usual "x" in W 2007. If no "x", is there a key stroke to close docs?
