Google AdWords Editor

I have a list of keywords involving the word "barcode."  I'd now like to make a copy of the list and replace "barcode" with "bar code"   doubling the total number of keywords.  I don't see a way to do this with AdWords Editor, though it seems there must be a way.  The best I've come up with is to copy the keywords from AdWords Editor, bring them into notepad++, double the list there, and import it back into AdWords Editor.

Thanks for any suggestions
