I just use the Center icon on the Word 2003 toolbar. The same for prior
versions as far back as I recall. If you do not have the Center icon on
your toolbar, just add it. In Word 2003, there is a vertical blue bar at
the right end of the toolbar. Click on the blue bard, select add buttons and
then formatting. Check the Center icon. If your current toolbar has too
many icons, you will need to delete one make room for the Center icon.
Deleting an icon from the toolbar is the same as adding one except you clear
the check box vice checking.
Suggest when you post that you mention your version.
