at the macro properties you can choose the context (2 step) and there is "Event choose...". In my german Version 126.96.36.1999499 is the option "group should be kopied (vetoable)".
I hope it helps you.
thank you! I actually work in 7.1.0 version, so I'm looking forward to 7.2.0 :)
It didn't work :( actually the macro with this context ("group should be copied (vetoable)") catches coping group and not moving it with mouse to another group. Did I miss anything?
