So I guess that the application is consuming that very keypress somehow by communicating with the X server (grab the key(s) in question). > However, with the application running in an X2Go session, the same > sequence of keys will trigger a switch to tty1-tty6 on the local client. The application probably also communicates with the X server which this time is nxagent. So nxagent would probably not pass the grab to the real X server. You could try if the coming autograb feature helps here. But for analysis we'd need the application to see what is doing. For the records: I think it is nx-libs so we should open an issue there. But I am not sure if we will be able to fix that at all. Uli
