One way to deal with increased sets of directly accessed letters is to map the
extended letters on the digits row, and to toggle between a languages layout
without directly accessed digits, and an ASCII layout, and to do this not via the
system facility, but with a hard-coded toggle on key E00. This way Iʼm catering for
French, [1] and I project to derive a Malian layout from it, but for Ga one has to
start from the US-English layout, except where French has been adopted in Ghana.

I see no particular challenges in starting from whatever layout to implement this
(including Vietnamese and Lithuanian, where digits are *already* on third level),
when the users are interested in a change for enhancement; but in adding an extra
row to a cellphone on-screen keyboard I do see several.

Kind regards,
