DefaultKeyBindings.dict file (~/Library/KeyBindings/DefaultKeyBindings.dict) for Mac OS X, created by Brett Terpstra and based heavily on work done by Lri.
Please note that these bindings won't work in all applications: TextWrangler and TextMate, for example, override these with their own settings.
See Lri's gists and website for more coding madness.
Installation: Copy the DefaultKeyBindings.dict file to the ~/Library/KeyBindings/ directory (create KeyBindings if it doesn't already exist).
Any open applications will need to be re-started before the key bindings will take effect -- or log out and log back in.
For more information, see my blog post, check out Macworld hints, an older but very relevant article from Harvard and do a search for more information.

This documentation is generated automatically from the comments and commands in the DefaultKeyBinding.dict file. The script document_keybindings.rb is free for use, but it's specifically designed for use with my formatting in the bindings plist (i.e. it's a little finicky).
