Scroll Automatically Through a Document
The Problem:
I work on longno, make that looooooongdocuments and need to scroll through large chunks of text to get my bearings on what's where. I've tried using the Document Map, but it doesn't cut the mustard for me. And don't suggest Outline view, either: I need to see the headings and figures in the document as I go.
The Solution:
Try AutoScroll. Choose Tools 
Macro Macros (or press Alt+F8), type autoscroll in the "Macro name" box, and press Enter or click the Run button. Word will display a "wait" cursor (the hourglass), but a shadowy double-headed vertical arrow will appear in the middle of the document window. Drag gently down (or up, if you want to scroll up) to start the scrolling. Drag further to scroll fasteryou may find the adjustment delicate if your computer has a fast processor and dual overhead camshaftsor drag back the other way to slow, stop, or reverse the scrolling. Click or press Escape to turn off AutoScroll.
If you like AutoScroll, put its command on a toolbar or menu. Choose Tools Customize, click the Commands tab, and verify that the correct template (for example, Normal.dot) or document is selected in the "Save in" drop-down list. Choose All Commands in the Categories list; then drag the AutoScroll item to the desired toolbar or menu. Close the Customize dialog box, Shift-click the File menu, choose Save All, and save changes to the document or template if Word prompts you to.
