Miscellany

• @notation{…} — refers to pieces of notation, e.g. ‘@notation{clef}’. Also use for specific lyrics (‘the @notation{A - men} is centered’). Only use once per subsection per term.
• @q{…} — Single quotes. Used for ‘vague’ terms.
• @qq{…} — Double quotes. Used for actual quotes (“he said”) or for introducing special input modes.
• @var{…} — Use for metasyntactic variables (such as foo, bar, arg1, etc.). In most cases, when the @var{…} command appears in the text (and not in an @example block) it should be wrapped with an appropriate texinfo code-highlighting command (such as @code, @samp, @file, @command, etc.). For example: ‘@code{@var{foo}}’, ‘@file{@var{myfile.ly}}’, ‘@samp{git switch @var{branch}}’, etc. This improves readability in the PDF and HTML output.
• @version{} — Return the current LilyPond version string. Use ‘@w{@version{}}’ if it’s at the end of a line (to prevent an ugly line break in PDF); use ‘@w{"@version{}"}’ if you need it in quotes.
• @w{…} — Do not allow any line breaks.
• @warning{…} — produces a “Note: ” box. Use for important messages.
