Not yet, but there will be. For the moment, anything you can set in CodeMirror's config ( http://codemirror.net/doc/manual.html#config ) you can set via `jsbin.settings.editor.[key] = [value]` and it'll apply it to the JS Bin editors.

There's a couple of others, and docs will be coming soon. In addition, there's an exposed API that allows you to point JS Bin to a JSON file and it'll load in and save those settings - which is useful for starting a class for teaching where you want the editor in the same mode across all the students.
