Did you know that if you are working on a Word document and you want to be able to see one part of the document while editing a completely different section, you can freeze a portion of the document on the screen? You can accomplish this dual view by dragging the little divider bar down from above the scroll bar.
FYI - this trick works in Excel as well. This way you can keep you column headings on the screen while editing detail cells way down the page.
Now you know, and knowing is half the battle
