Since this post is a month old, I presume you found your solution. If anyone is still wondering how to do this, you can add something similar to the following to your User Key Bindings file (on my windows machine it's at C:\Users\myusername\AppData\Roaming\Sublime Text 2\Packages\User\Default (Windows).sublime-keymap--or just select Preferences|User Key Bindings):

{ "keys": ["ctrl+shift+w"], "command": "toggle_setting", "args": {"setting": "word_wrap"} }

Hope this helps,
