I could have edited the xkbd layout file , and altered it to provide the 'F' keys ... But then I would have needed to figure out the correct command protocol to launch my layout , and it was 2.30am with me needing to be up at 6.30am for work ... So I deleted the lot , and have given up for now . Perhaps a cleverer person than I will have the inspiration to get this all working together , the Psion Series 3a emulator will run on the Nokia , it probably only needs polishing up a little , sadly I don't understand enough about Linux to do that polishing . Should anyone else have managed to figure all this out , please get in touch .
