Yes, this was my intention. If I type "×" (the times sign in Latin-1,2,3, and 4) I want that it works both in text and in math mode giving something sensible (i.e. \textmultiply or \times resp.) I don't want to have the command \times in text mode and \textmultiply in math mode necessarily (though it might lower the burden of memorising commands). > \DeclareInputTextAndMath{<somenumber>}{\textalpha}{\alpha} > > you may have meant that as well, have you? Yes, and the syntax looks fine to me. --J"org Knappen P.S. > [...] i strongly plea for math only accepts the small set of real > ascii, ie > > 0-9 a-z A-Z !"/()=?`'+*<>|,;.:- > plus commands > > by default (repeat: default). There are two characters which are pretty useless in math, namely '"' (the double quote) and '`' (the grave accent). The former fact is real good luck because it allows TeX fomulae in HTML ALT-tags without breaking HTML syntax. The later is just a cutiosity, but without AMS fonts there isn't any sensible symbol mapping to '`'.
