I use the mentioned "It's all Text" in Firefox (to pop open gvim) alongside another addon called "Vim Fx"; these two addons together provide for a far superior experience than the vanilla iPython notebook. Though I'm still hoping they integrate vim keybindings eventually -- I've noticed that there are some branches on github w/ these, but can hardly wait to see that kind of thing surface in master.

Awesome, didn't realize it worked in pentadactyl as well.

One small caveat: i use macvim, it opens a new window in macvim, i close/sync it with :wq. Any idea how I can have it so it jumps back to the firefox window instead another macvim window?
