Yes, it's possible! If you're like me you want to spend as much time in vim as possible. While I appreciate CKEditor on MDN, I personally prefer to edit text in vim, and I think many developers might agree. And since MDN should include content written by developers for developers, here's a way to edit your favorite web developer docs (that would be MDN), using vim. (In my case, MacVim)
- Install the It's All Text Firefox addon.
- Go to the IAT preferences
- set your editor to vim (MacVim.app in my case)
- set your hotkey. (alt+command+e in my case, now that I'm used to Firefox Dev Tools "Inspect" and "Console" keyboard hotkeys)
- Go to the MDN article you want to edit. (Apps/Getting Started in my case)
- Click Edit (duh)
- Click Source
- Type your hotkey!
- Drink beer and edit away!*

Note: For MacVim you may need to set the "After last window closes: Quit MacVim" preference so it puts you right back to Firefox when you :wq.
