Thanks for the reply. This would definitely help if my mouse is broken but I was looking for the shortcut, as you can tell.
It is surprising to me that there's one to create a new flow in the Workspace window (Ctrl + N) but (apparently) not one to create a new subflow in the Designer window. I say it is surprising because users would create way more subflows than flows throughout a development cycle.
If this doesn't exist I would strongly recommend adding one. Is there a way to officially ask for this?
