Shortcut for creating a new file?

Is there a quick way to create a new file when the file pane is collapsed? I often work with it closed, and if I want to quickly make a new file I have to 1) toggle the file pane, 2) click the + icon for creating a new file, and then 3) collapse the file pane again.

I see a couple of requests on the forum for a new file keyboard shortcut, so I assume there still isn’t one. Is there another way to quickly create a new file—maybe by a URL scheme?
