Re: Override KeySignature end-of-line-invisible

[tisimst]

As explained in the docs:

http://www.lilypond.org/doc/v2.18/Documentation/notation/visibility-of-objects#special-considerations

the syntax \override Staff.KeySignature.break-visibility = #...

only affects the key signature at the beginning of the line (not sure why, but that's what it says). The correct syntax, it says, is

\set Staff.explicitKeySignatureVisibility = #end-of-line-invisible

which works for me.

I am quite sure that I am improperly applying the method to make invisible the key signature at the end of a line when the key changes beginning on the next staff.

The code below shows my attempt to use the method in two different manners at several points.  I have commented out the non-working code.  However, compilation works fine.

I don't actually know which object I am to be overriding and which is proper syntax.  I have seen several examples written in the forms I have shown.  The ??? is my indication of "Which" object?

  c1:maj7 d:m7 e:m7 f:maj7 g:7 a:m7 b:m7.5-
 \break d1:maj7 e:m7 fis:m7 g:maj7 a:7 b:m7 cis:m7.5-
}

upper = \relative c' {
  \clef treble
  \key c \major
  \time 4/4
  <c e g b>1 <d f a c>1 <e g b d>1 <f a c e>1 <g b d f>1 <a c e g>1 <b d f a>1
