    Yep, we have only the c-cedilla in a separate key. Everything else is made
    with dead keys, which (as said) produce every combination cp-1252
    includes, even those not used in Portuguese (this is about the most usual
    105-key windows-PC keyboad and its driver, whose real name I forgot).

    Aftear reading the interesting parallel thread about french keyboards, I'm
    sure that the portuguese keyboard is much better to type French than most
    french keyboards... ;-)

    This happens with my current keyboard configuration, actually. I have nine
    dead keys (actually three keys in three shift states) and they all result
    in diacritcals over the following letter, either Unicode precomposed or
    with combining diacriticals Quite funny for unadvised users making typos.

    In Portuguese, this will happends with "a" and "o". People are used to
    type [dead key] [space] [letter].

    Jukka, I like your ideas! :-) I more or less did this with Keyman (version
    6.0), bit it still has some problems with AltGr, cursor keys, NumPad, etc.
