@c Is there a way to have a final bar ("|.") at the end of the
@c previous line? Doesn't seem to be.
+@c It could be done by overriding
+@c the BreakAlignment property. Want a separate example?
If you want to start a repeat at the beginning of a line and have a
double bar at the end of the previous line, use @code{\bar}. For more
information, see @ref{Bar lines}.
@funindex repeatCommands
-@c FIXME: Markup does not work in the "text" field
-@c And how does one change the font?
-@c On the whole, this section needs better documentation (why the
-@c double parentheses around the volta expressions?)
+@warning{These methods are only used for displaying unusual repeat
+constructs. In most cases, repeats should be created using the
+standard @code{\\repeat} command or by printing the relevant bar
+lines. For more information, see @ref{Bar lines}.}
The property @code{repeatCommands} can be used to control the
layout of repeats. Its value is a Scheme list of repeat commands.
-@table @asis
-@item @code{start-repeat}
+@table @code
+@item start-repeat
Print a @code{|:} bar line.
-@item @code{end-repeat}

-
-@item @code{(volta @var{text})}
-Print a volta bracket saying @var{text}.
-
-@item @code{(volta #f)}
-Stop a running volta bracket.

+
+Text can be included with the volta bracket. The text can be a
+number or numbers or markup text, see @ref{Formatting text}. The
+simplest way to use markup text is to define the markup first,
+then include the the markup in a Scheme list.
