        !            44: % --If you don't work with ednotes, only with lineno, you 
        !            45: % get the main feature of making \linelabel work in math mode 
        !            46: % by loading lineno.sty--version 4.1 onwards--with its 
        !            47: % package option `mathrefs'. 
        !            48: % 
        !            49: % * Switch off and on: * 
        !            50: % To reduce danger resulting from missing error messages 
        !            51: % ("caveat" above), you may switch these new math facilities 
        !            52: % off by \NoNotesToMath where you don't expect to need them. 
        !            53: % You may switch them on again by \NotesToMath where you want 
        !            54: % to use them, being aware of the danger. Both commands work 
        !            55: % locally, so you can replace one of them by enclosing it in 
        !            56: % a group. E.g., even, after \NoNotesToMath you can use an 
        !            57: % environment as follows: 
        !            58: %   \begin{NotesToMath}

        !            62: % 
        !            63: % * Customize ellipsis: * 
        !            64: % ednotes' \lemmaellipsis is changed to expand to 
        !            65: % \mathlemmaellipsis when entering math, and this is preset 
        !            66: % to be LaTeX's \mathellipsis. (This is three dots as 
        !            67: % \mathinner.) You can change this by redefining 
        !            68: % \mathlemmaellipsis, e.g.: 
        !            69: %   \renewcommand{\mathlemmaellipsis}{\cdots}
        !            70: % If you need \cdots as the ellipsis at a single place only, 
        !            71: % you may, of course, use the `<...>' option of \<, e.g.: 
        !            72: %   $ x = \Anote{a\<<\cdots>bcd\>e}{Indeed?} - y $
        !            73: % 
        !            74: % * Customize note mode: *
        !            75: % For variant readings, you may want that the note is 
        !            76: % usually set in math mode--so you may want that you 
        !            77: % needn't type the dollar signs in the note text. 
        !            78: % Note that you can do this by customizing \notefmt, 
        !            79: % and you can do this by customizing \Anotefmt (e.g.) 
        !            80: % to have this feature for \Anote only.
