Like in GTK+ `Ctrl+Shift+U hex RET' http://en.wikipedia.org/wiki/Unicode_input
we could finish entering the number with RET, e.g. `M-2 M-7 M-0 M-f RET'.
Or expect a fixed-length four-digit number `M-2 M-7 M-0 M-f' where the last
fourth digit finishes the sequence.  In any case, your up/down events code
would be useful for other purposes as well.
