Hi Lighthouse,
You can use the Range object, but the routine I wrote (using the Selection
object) will work just fine. wdStory is a constant. Basically, anything in
Word VBA that starts with "wd" is a constant.If you want to know what a
constant does, then look in the help not for the name of the constant, but
the name of the method or property associated with the constant. In this
case, you would look for "HomeKey". In short
With Selection
   .HomeKey Unit:=wdStory

sends the cursor to the beginning of the document. If you're only interested
in finding the first occurrence of "styleX", then send the cursor to the
beginning of the document (shown above) and then search for the style from
there (shown below). You can find "With Statement" in the VBA help file.
Take the following example:

With Selection
   With .Find
       .ClearFormatting
       .Text = ""
       .Style = "body text"
       .Replacement.Text = ""
       .Execute
   End With
End With

Pretty easy to read, isn't it? Well, you can accomplish the same thing with
Selection.Find.ClearFormatting
Selection.Find.Text = ""
Selection.Find.Style = "body text"
Selection.Find.Replacement.Text = ""
Selection.Find.Execute

As I hope you can see, it's a little more difficult to read. BTW, it also
takes a little longer to execute. The With statement, then, does at least
two things, it makes your code a little more readable (and, therefore,
easier to maintain), and it makes your routine (especially longer ones) more
efficient in terms of execution time because "fewer dots" in a line of code
execute faster.

HTH,
Dave
