Are you working with PDFs? Are you trying to change content on the PDF page itself? If so, you are going to have to place a text annotation on top of the F# with a white background, and enter in Gb as the text.

Thanks Mike. When you say "with a white background", would this emulate using "white out" on paper sheet music? Or are you saying that I can't change the F#, but I can make a note to myself above the staff?
