Segno or coda on top of rehearsal mark

Starting with LilyPond 2.24 the \textMark command and the normal \mark command happily coexist. Furthermore, the sophisticated \repeat segno command is available. (Be sure to look at the English version, since translations of the Notation Reference might not be up to date.) Consequently, this snippet is much shorter in comparison to previous versions in the LSR.

\version "2.26"

markDefault = \mark \default

markDefaultSegno = {
  \textMark \markup \musicglyph "scripts.segno"
  \mark \default
}

markDefaultCoda = {
  \textMark \markup \musicglyph "scripts.coda"
  \mark \default
}

\score {
  \relative c' {
    c4 d e f
    \markDefault

  }
