Is there a way to bind a key via the command line?

[sunbeam60]

I'm using Micro as my Midnight Commander viewer (in read-only mode, with a different theme to avoid confusion).

When it's acting a viewer, I'd love to use Escape to quit (whereas in editor mode, clearly that's not super smart given it's also how to get out of command mode).

I think the only way to do it is to specify a different config-dir and then bind the Escape key in the bindings.json in there.

But it would be ideal if there was a way to bind a key via command line invocation, so I didn't have to keep two sets of config files in sync, just to achieve the "Escape":"QuitAll" binding in there.

I don't think that's possible however, but is there something I've missed?
