Earlier, I posted a useful link at Rubicon Computing Solutions for a poster of all the keyboard shortcuts in the Visual Studio IDE. As I was looking for some more neat shortcuts, I came across this site with more useful tips -- mainly, how to enumerate all the shortcuts, and how to customize them.
I have had many occasions to have to remap the shortcuts, primarily related to add-ons I have placed in my IDE. The macro in the referenced Microsoft link will help show what the current mappings are, which would be extremely useful if you needed to do a lot of remapping.
