Sorry, but I am finding this more and more pointless.

You have not given any real reason for doing this. I am also a bit off with your statement:
However I am looking for something faster which would be similar to the find all instances which is available from word xp and on
Does that mean you are using 2000 or earlier? These pieces of information are important to tell us when you post.

I also think it very strange that you are trying to compare Adobe InDesign with Word. If this is what you are doing, then tell us...

Give me real numbers. HOW slow? What IS the difference? These vague comparisons, and vague (or NO) explanations of what you are wanting to do - REALLY want to do. Besides, it is silly to compare a layout application (Adobe InDesign) with a word processor (Word). They are very very different beasts.

Well, I think I am done here.

The bottom line is - I don't see the point of what you are doing, you have been given exactly what you asked for, and so.....

Good luck.
