I've been using this AutoHotKey script long enough that Ctrl+Shift+V has become a muscle memory for "paste without formatting". In case it's useful to anyone else, put this in a file (clipboard.ahk) and run it at startup:

  ^+v::
  Clipboard:=Clipboard
  Send ^v

That way, it works globally, it's not dependent on any particular application implementing it.
