+Custom marks can be used as alternatives to numerical marks, and the
+annotation line joining the marked object to the mark can be
+suppressed:
+
+@lilypond[quote,verbatim,papersize=a8landscape]
+\book {
+ \header { tagline = ##f }
+ \relative c' {
+ \footnote "*" #'(0.5 . -2) \markup { \italic "* The first note" } a'4
+ b8
+ \footnote \markup { \super "$" } #'(0.5 . 1)
+ \markup { \super "$" \italic " The second note" } e
+ c4
+ \once \override Score.FootnoteItem.annotation-line = ##f
+ b-\footnote \markup \tiny "+" #'(0.1 . 0.1)
+ \markup { \super "+" \italic " Editorial" } \p
+ }
+}
+@end lilypond
+
+More examples of custom marks are shown in
+@ref{Footnotes in stand-alone text}.
