[DHowett-MSFT]

We didn't commit the keybinding constants in with which people could opt. ☹️

I noticed that @zadjii-msft added the keybindings for panes back. I'm assuming it made it into 0.1.1621.0?

If I add this block:

                "command" : "splitHorizontal",
                "keys" : 
                [
                    "ctrl+shift+-"
                ]
            },
            {
                "command" : "splitVertical",
                "keys" : 
                [
                    "ctrl+shift+|"
                ]
            },

Only Horizontal works. I noticed that if I close Windows Terminal it deletes the splitVertical keybinding from profiles.json.
