I brought this up when on the CityEngine Beta for 2019.1 and was hoping it would be addressed in 2019.1 release but sadly its not - I cannot Cmd-Z to undo inside of CityEngine. I've uninstalled, reinstalled and reset keyboard preferences. I've tried to remap the command in preferences and This might has to be the most critical shortcut key - it makes CGA coding just about impossible.
You can see here there is no shortcut key showing for undo
But everything looks fine here....and even if I rebind the keys, it simply does not work. Very very frustrating. And I would say makes CityEngine on the Mac unusable, at least for me. Anyone have any ideas?
