    The legal obligations method has often trouble to get working with
    computers, the latter which evolve so fast.

    As you point out, it is important to find some solutions that really
    work. Then people will start using them.

    The reason I am sceptical about keyboards with LED's/LCD's on the
    keys is that there is a development principle that speaks against it:
    In the long term, products are promoted having fewer mechanical
    components. By contrast, the number of transistors on a chip is
    mainly limited by development costs. Once those have been paid, a
    chip costs about the same regardless whether it has many or few
    transistors. So fly-by-wire airplanes has a long term development
    advantage over mechanically controlled ones. The same the applies to

    So touch screen type keyboards should have a long term advantage over
    mechanical keyboards with LED's/LCD's one the keys, provided the
    feeling feedback to the human problem can be solved.

    With the Ukelele suggestion, I have started thinking a bit on
    keyboard character layouts for math. Then I would want to have more
    modifier keys for the Math Alphanumeric Symbols. For the other math
    symbols, there is a real problem trying to find logical positions.
