In Word 2000, you can simply choose Format » Style to display the Style dialog box, choose "All styles" in the List drop-down list, select Document Map in the Styles list, and click the Modify button to modify the style.
Word 2003 and Word XP hide the Document Map style and some other built-in styles from you. To force Word to display the Document Map style:
Choose Format » Styles and Formatting. In the Styles and Formatting task pane, choose Custom in the Show drop-down list to display the Format Settings dialog box.
In the "Styles to be visible" list, check the Document Map box, and then click the OK button.
Back in the Styles and Formatting task pane, click the Document Map style, click its drop-down arrow, and choose Modify from the pop-up menu to display the Modify Style dialog box.
Once you've opened the Modify Style dialog box, use its controls to modify the style. Check the "Add to template" box to make sure your changes are saved to the template.
Scroll Automatically Through a Document
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.
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.
