Writing the settings

Textmate's tutorial may help you.

You may want to look up in Apple's document for Function-Key Codes (see Constants > Function-Key Unicodes) and Cocoa Event Names (see Instance Methods).

Applying the settings

Put this file under ~/Library/KeyBindings/DefaultKeyBinding.dict and restart a Cocoa Application.

Known Issues

This hack makes Home and End key not working in the address bar of Firefox. (It's not a native Cocoa Application)
