DefaultKeyBinding.dict file (~/Library/KeyBindings/DefaultKeyBinding.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.

Installation: Copy the DefaultKeyBinding.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.

The repository includes a script to generate a Dash docset from your customized version of the file. See here for details.
