If you'd like to properly remap move to next/previous word and other commands in Mac OS X, I'd recommend Karabiner (which was previously called KeyRemap4Macbook).

https://pqrs.org/osx/karabiner/

I use it to map the emacs navigation keys for use across the OS, and find it really improves my experience. If you're interested in that set up, I use the following options, which are all listed under Emacs Mode: - Control + PNBF to Up/Down/Left/Right - Control + A/E to Command + Left/Right - Option + B/F to Option + Left/Right - Control + D to Forward Delete

Of course, I have caps lock remapped to Control.

There are also Vi remap options in Karabiner, plus tons of other stuff.

Disclaimer: I'm a bit of an emacs lightweight, so it might be that the remapping options aren't as full-featured as what a more advanced user would like.

I use KeyRemap4Macbook for a variety of purposes, mostly related to making a PC-style USB keyboard play nicely with OS X. It doesn't go as far as I'd like, though.
