VS2008: Bookmarking & Good Practices Question

Forgive this naive question:
Of what use is the "bookmark a line" option in VS2008?

Please tell if you know any good programming practices in VS2008. To clarify I would like to give an example:
A Windows XP user should know what msconfig is, in order to optimize the performance of his OS. The following link mentions some XP tweaks:

Is there a similar link for VS2008?

Regards,

Bookmarks allow you to jump through different parts of your code, that you (book)mark. It is a helpful way to quickly switch from one part to another.

As for the other question, I don't see any connection between good programming practices (in VS2008?) and operating system tweaks. :(

Thanks! Those links are real good.
I have tried asking people about resources on good tips. But I end up getting unrelated answer. This time again, it seems, my example was wrong but those links are exactly what I was looking for! :)

For "tips and tricks", you could take a look at this link:
