Positioning segno and coda (with line break)

If you want to place an exiting segno sign and add text like “D.S. al Coda” next to it where usually the staff lines are you can use this snippet. The coda will resume in a new line. There is a variation documented in this snippet, where the coda will remain on the same line.

\relative c'' {
  c4 c c c | c c c c |
  \repeat segno 2 {
    c4 c c c | c c c c |
    \alternative {
      \volta 1 {
        c4 c c c | c c c c |
        % If you don't use \break at Coda, use \noBreak here
        % and after \bar "" below.
        \noBreak
        \section % double bar line
        \cadenzaOn % pause bar count
        \stopStaff % remove staff lines
        % Increasing the unfold counter will expand the staff-free space
        \repeat unfold 4 {
          s1
          \bar ""
        }
        % Place JumpScript where the staff would normally be.
        \once \override Score.JumpScript.outside-staff-priority = ##f
        \once \override Score.JumpScript.Y-offset = 0
        \startStaff % resume bar count
        \cadenzaOff % show staff lines again
      }
    }
  }
  \sectionLabel "Coda"
  % Show Coda on a new line
  \break
  \repeat unfold 6 { c4 c c c }
