So while you can do either of these
- right-click and choose Open with
- you can go to the menubar and choose File > Open With
Just checking the Edit Keyboard shortcuts window under the File menu, there's no listing for Open With. I guess given that there's no way to say for certain what applications would be available on any given computer. So bar a custom app on the PC side that does user-defined keyboard shortcuts to match your setup... there must be one.
