Is this Word 2007? Then you should right-click the bulleted paragraph and
choose Adjust List Indents from the context menu. In the dialog box, "Bullet
position" is the distance from the left margin to the bullet character;
"Text indent" is the distance to the text from the left margin. For a
hanging indent, you would specify a larger value than for "Bullet position."
For "Follow number with," choose "Tab character." Select "Add tab stop at,"
and then specify the same value that you chose for "Text indent." When you
are done, click OK.
