[IPython-dev] Emacs/Vim keybindings in the notebook

[Brian Granger]

Fernando,

I am working on the client side configuration stuff.  But a temporary
fix would be to allow these things to be configured using the
Javascript  API.  Something like:

IPython.notebook.enable_vim_kb()
IPython.notebook.enable_emacs_kb()
IPython.notebook.enable_default_kb()


That is much better than forcing a user to edit the source code.  That
is currently how I am handling things that need configuration.  A JS
API until we get the config UI done.  I wouldn't even mind merging
this type of thing into master so users can start to play with it.

How does that sound?

Cheers,

Brian
