Rename Global Label

Is there a way to do SEARCH & REPLACE just about anything in KiCad. Example: I have a Global Label Named “+9V” (maybe on 30 places in the schematics) which I want to rename to “+7V” in hopefully just one SEARCH/REPLACE (Find/Replace). How?

Did you already try using the Find/Replace feature?

Ah, too simple and close once again! Thanks craftyjon.
