Are you referring to using TAB and SHIFT+TAB to demote and
promote numbered lists and/or to set indents? If this is the
case, try the following:
For Word 97 and Word 2000: Tools | Options | Edit: "Tabs and
backspace set left indent."
For Word 2002 and Word 2003: Tools | AutoCorrect | AutoFormat As
You Type: "Set first and left indent with tabs and backspaces."
