One option is to use the "n" option for the K validation strings,
which reports all keypresses in the icon to the task. You can then
respond to the keys 0 to 9 being pressed by setting the writable icon
contents to that value, no matter what it was before.

I cannot remember whether the Wimp will pass the keypress on if it has
handled it itself, so you may need to force this by setting the
allowable characters to something *other* than 0-9. Perhaps "A Kn" if
you don't mind space being entered.
