Thanks Steve, but I don’t think I made my question clear. I have a Key Command (I use Ctrl+R) assigned to Activate the Arranger Track and sometimes use the On/Off button on the “old” F2 transport control. That part is fine. I use it all the time, Activating is not the problem.
I want to open the Arranger Editor without having to select the Arranger Track. None of the key command options under “Arranger” include Open Arranger Track Editor. Preferences under “Editors” include many Cubase editors, but not the Arranger Editor (also not present are the editors for – Markers, Tempo, Signature).
