Scrolling PDFs In Other Windows (opens in new tab)

Marcin Borkowski (mbork) has a useful post on scrolling PDFs in the other window. He wants to use the familiar Ctrl+Meta+v and Ctrl+Meta+Shift+v shortcuts for pdf-tools. Sadly, these don’t work for scrolling PDFs but as mbork says, “… [I]t’s Emacs, so it shouldn’t be difficult…”. And, indeed, it isn’t.
