I have used that hold state inside of macros but never from an outside prespective.
YEP testing shows it certainly will allow outside movement while in the hold state (;-)
SO as long as I don't have any other macros running concurrently that use that approach then 1 button it is (;-)
Now the plasma G68 part rotation is a 1 button option.
Thanks Ian, I learn something new almost every day, (;-)
