You can enable as much vi mode as possible with your ~/.editrc file. Try doing:

$ man editor

There are many things you can add keyboard shortcuts for and this man page details them all. We seem to have a mixture of both emacs and a few vi keybindings by default. Everything is exposed and can be remapped in your ~/.editrc file. If you come up with a list of vi shortcuts you think others might want, send a reply email with what you found.
