From your link:
"WARNING: Editing your Windows registry may cause unintended side effects that render your system inoperable. Although this tip has worked in the past for some people, there is no guarantee that it will work for you. Use with caution, and at your own risk."
As a Windows admin, that is what I would tell you if you came to me with this issue. You want to play with the registry following guidelines from a UNIX editor website, go ahead, but if it breaks something, it is going right back to the way it was.
After the wrist-slapping was out of the way, I would recommend a solution anyway (because I am nice) that doesn't involve manually editing the fundamentals of Windows operation. This is also from your link:
"As an alternative to changing the registry, there are various utilities that can remap keys. Many of these can be run by a non-administrator, and can apply mappings only when wanted (for example, when running Vim). They do not require log off/on or reboot to apply changes."
Come to think of it, maybe you could get a better response if you ask this question on http://stackoverflow.com/ instead...Sysadmins can be a little sarcastic and testy about stuff like this :)
