Over at the How-To Geek's home away from Lifehacker, blogger Mysticgeek points out a Word 2007 tip many of us had no clue about—you can edit a document in Print Preview mode by turning off the "Magnifier" switch.
Print Preview is how you get a look at what a document will look like in actual paper form, and can reveal margin problems, font discrepancies, and other problems. Problems we'd thought, until this morning, you had to switch back into an editing view to fix, then return for the overhead view. Un-check the "Magnifier" option in the Print Preview ribbon, however, and you'll get access to your words again.
You won't have your full ribbon of editing tools handy, but you can access most of them through the right-click menu, and make basic typing changes to your heart's content, all while keeping an eye on what the page actually looks like.
