My interest is on the Windows platform. I'm cross compiling on Ubuntu 16.04. The problem regards keyboard shortcuts in the windows environment. All the shortcuts requiring the user to press the AltGr modifier do not work. In the current version of OpenSCAD there are two of them if you are using an italian keyboard: zoom in and zoom out. I suspect many other keyboard layout do have the same problem On Wed, Jun 29, 2016 at 11:50 AM, tp3 [via OpenSCAD] < ml-node+s1091067n17829h74@n5.nabble.com> wrote: > Von: "Rogier Wolff" <[hidden email] > <http:///user/SendEmail.jtp?type=node&node=17829&i=0>> > > No. this is not feasible.

The issue sounds like a variation of that one: https://github.com/openscad/openscad/issues/872 This might make it pretty much impossible to use the AltGr modifier for anything unless it's actually user configurable. Unfortunately I have not seen any re-usable component or library to that yet, so we may have to implement that ourselves eventually. ciao, Torsten.
