Work in Two Parts of a Document at Once
The Problem:
I often need to work in two parts of a document at the same time. I'm getting whiplash from flipping back and forth.
The Solution:
Split the window (choose Window 
Split) or open a second window (choose Window New Window). You may sometimes need to use both multiple windows and splitting when working with complex documents.
Tip: You can use the Virtual Desktop Manager PowerToy (http://www.microsoft.com/windowsxp/downloads/powertoys/xppowertoys.mspx) to run two or more virtual desktops.If you're generally underwhelmed by Word's navigation and editing features, check out WordToys (http://www.wordtoys.com). There's a free version that offers a wide variety of appealing enhancements, and a Professional version ($20) that provides even more.
