You can do this by creating your own normal.dot template.
You can set the tabs, the margins, the font, etc., in a
new document, and save it as normal2.dot. Then go into
your templates directory using the Windows Explorer/File
Manager, find and delete the normal.dot, and rename the
normal2.dot as normal.dot. You will now have a new
normal.dot template that has all of your cuctomized
settings.
Cordially,
