Which file are custom keyboard mappings saved?

I just did a nuke-and-pave of my OS (macOS) and realized until it was too late that I forgot to export my custom Resolve 15 keyboard shortcuts to a standalone file.

I still have the backup clone of my previous system, so I can still access all the previous settings, but since I cloned it to a sparsebundle instead of an actual bootable partition, I can't boot back into it to re-export the file.

Is there a specific file buried in the Resolve settings/preferences heirarchy that I can just copy over and overwrite on the new system that contains my custom keyboard shortcut settings?
