Re: [Builder] Emacs mode and keybindings

[Christian Hergert <christian hergert me>]

Thanks for doing this Alex!

I am curious if it is possible to do the same with VIM mode. It has a
lot of very strange interactions that are not exactly doable with
G_SIGNAL_ACTION. When I tried to do a few things, I simply couldn't get
it working. But that was months ago, and my mind slips as to why. I
might have just moved on to other things due to the level of importance.

Cheers,
