I think we might be talking at cross purposes here; we only have what I
think you cal the matrix keys (and I call the keypad) working; the
buttons on the top of the device itself. We haven't got the mailboard
working yet, though Matt Callow has worked out the GPIO pins and started
trying to plumb it into the serio infrastructure. Thus I was suggesting
"abusing" some of the keys on the keypad for more useful characters
until we get the mailboard operational. Of course that might happen over
the weekend. :)
