Where does MonoDevelop v4+ save key bindings?

In older version of MonoDevelop, there was a key bindings XML file in the MonoDevelop preferences, in the ~/Library/MonoDevelop-3.0/KeyBindings folder on a Mac. (For details, see here.) In my current version of MonoDevelop, however, there is no KeyBindings folder and I can’t see any other place where key bindings are saved.

So the question: where are key bindings saved now?

The reason I ask is I’d like to export and version control these keybindings.

I’m running in Windows, but this appears in the following URI C:\Users\AppData\Roaming\MonoDevelop-Unity-4.0\KeyBindings

And only seems to have modified key-bindings. Hope this helps others.
Next time I have time & access to a Mac I’ll see if I can find where it’s stored on Mac OS FS.
