I do not believe that this statement would act on a separate instance of Word - unless you were already holding a reference to it - in which case I wonder why you are creating a new one.

As you have discovered, Gerry was correct to tell you to qualify the reference with the application. I am surprised he did not tell you to use:
[vba]wrdDoc.Range.Find[/vba] but none of use are perfect :-)

The Selection is what is displayed on screen, what the user interacts with. There is a significant overhead in using this when you do not want to interact with the user.
