Ignacius is absolutely correct. This wont make any difference in typical point and click usage for exactly the reason given. Whilst an empiric approach is cool simply because it's a good way to learn, there are times where it is indeed better to discuss than to try. Although I'm just a stranger from the internet, I've been smacking my head against this whole Unix thing for near on 2 decades, I do feel this is one of those times that it's better to understand why it wont make a difference than to try and see if it does.
