Control-Scroll tricks
Actually, this isn't just Word, but Word is my favorite place to use it. If you want to quickly reduce or enlarge the view on your screen, hold down the Control button and scroll with the mouse. You can adjust in small increments (much easier than using the set amounts in Zoom, or typing in a custom percentage). In addition, you can use this for a QUICK "print preview." It takes only a split second to reduce from 100% all the way down to thumbnails. Also, this uses one of my favorite techniques. I'm neither a mouse-only nor a keyboard-only person, and I love quick tips that enable me to use a left-hand keystroke with a mousing action. The control-scroll action works in Outlook (within a message), PowerPoint, Excel, and Internet Explorer.
