Sibelius 7 score key sig changes

Question

I'm changing from F Minor to Major in a Sib 7 score. The machine just gives one flat for the new section, and I want three naturals and one sharp. How do I get it to do it? Any ideas?

Answer 1

F Minor has four flats in its key signature. F Major has one flat. You say want three naturals and one sharp. Do you mean three naturals and one flat? (Hope so!)

By default Sibelius has Cautionary Naturals turned off:

And the stave looks like this:

With Cautionary Naturals turned on, the stave looks like this:

Answer 2

Turn on 'Cautionary naturals' in Engraving Rules/Clefs and key signatures.

But maybe the information that, despite what we learned for our Grade 5 theory exams all those years ago, it is now acceptable to omit them will be sufficient?
