No, no, I didn't want to go that far ...

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).

Yes, and the syntax looks fine to me.

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 '`'.
