I am using Build on both a Windows machine and a Mac (both Chrome, not the dl'd app). The help pane seems to indicate that 'cloning' a question should be possible - that is, if you drag and drop a question while holding the option key on mac, you will get a duplicate of the question instead. Am I reading that correctly? It would be very helpful, but I'm not getting it work - is there a particular order to clicking, etc.? Or is that a feature that currently works in the browser?
