As you know you can split an Editor window in two parts. So I can edit one part of a file and look at another of same file at same time. That is a great feature.
How can I move one part to another monitor?
Or is it possible to open the same file twice?
Under the menu item Window, select “New Window”. Make sure the tab you want duplicated is selected.
The new window can be dragged on to the other monitor.
