How to Change the Default Tab Stops in Word 2007
Word 2007 automatically sets tab stops for you in each new document you create. These default tab stops are set at half-inch intervals, but you can also create your own tab stops.
Click the Dialog Box Launcher button in the lower-right corner of the Paragraph group, on the Home tab.
In the Paragraph dialog box, click the Tabs button.
This is located in the lower-left corner of the Paragraph dialog box. The Tabs dialog box appears.
Create new default tab stops.
You type the new default tab stops in the upper-right corner of the Tabs dialog box. For example, to set the default tab stops three-quarters of an inch apart, type 0.75 in the Default Tab Stops box.
Click OK to confirm.
Then close the Tabs dialog box. The default tab stops appear as dark brown ticks (they’re very hard to see) on the gray line below the Ruler.
When you set your own tab stops, Word removes the default tab stops between the left margin and wherever any tab stop is set.
