Editor key bindings, vim, emacs, custom?

I’m using the in-browser html editor for the very first html challenges. Are there are any navigation hotkeys I could use to get around?

The FCC in-browser editor is a CodeMirror instance. Taking a quick peak at the FCC repo, it doesn’t look like the vim, emacs, or sublime keymaps have been used. If you have an editor you’re comfortable with, you can always work in it and then copy your solution into the FCC editor (this has the added benefit of encouraging people to save copies of their work).
