Space between clef and key signature accidentals

Hey there!
Is it possible to specify the distance between the clef and the key signature accidentals in the “preamble”?

Thanks!
Albert.

Yes.
It’s on the Spacing Gaps page of Engraving Options, the second setting in the second section: Gap after initial clef. It affects the gap between the preamble and the first note if there’s no key signature as well.

Oh! Thank you very much, fkretlow!
