Hello Hans, just back from the lecture I have given and I got an idea: Take not that keyboard of you, but take the Maximus (1430 euro!) or the Tactus, see http://www.artlebedev.com/everything/optimus/aux/ Prepare with ConTeXt a number of keys, for instance parts of mathematical formulas and functions, or parts of molecules out of the chemistry. Put them in the keys of one the keyboards, mentioned above and there can be given a lecture with readable formulas. By touching those keys you get a nice written text. Or some key, that you get a nice table ( prepared by ConTeXt) at the screen. And such that it can be filled by handwritten information, using some tablet or otherwise. May be it is already possible for a virtual keyboard on a touchscreen or something like that. A ConTeXt package for the preparation of the keys of a virtual keyboard? It is just an idea, really I have no idea how to realize it, Kind Regards, Rene'
